In today’s devlog, we are discussing one of the most important aspects of Nightmare Circus: the bosses’ design philosophy. During their development, we wanted to prioritize two main aspects for the biggest challenges: memorability and teaching the players.

In Nightmare Circus, bosses and mini-bosses were never meant to be simple obstacles for players to overcome. They were created to be a means to learn the mechanics progressively.
Through their moveset and abilities, they will make sure that you will master step-by-step the optimal actions that will defeat them, and eventually help you in future levels…

Just as important, they must be memorable characters.
If a boss is meant to test the player’s understanding, its identity must communicate that purpose instantly through shape, silhouette, movement, and atmosphere–even before the fight starts.

Every time the designing process for a boss in Nightmare Circus, begins with a single question:
What is this boss teaching the player?

The answer to that question defines everything, from proportions and posture to animations and the timing of their entrance. We intentionally design bosses with strong, readable silhouettes: exaggerated limbs, theatrical poses, and movements that can be understood at a glance. Players should feel the danger of a boss before fully understanding it, and realize they are in for a greater challenge.

Beyond clear proportions, our boss designs are shaped through close collaboration between the gameplay team and the narrative team. We want to ensure that every character is not only functional within the combat system, but also faithful to the story, personality, and emotional direction established by the narrative.

Color choices, materials, surface details, even small elements like stitched seams or dangling parts are all designed to reflect each character’s theme and state of mind. Color is not only used to separate enemies from the environment, but it also reinforces mood, emotion, and the tone of each fight. Our goal is for players to do more than just fight a boss; we want them to slowly fall into that boss’s nightmare stage without even realizing it.

While Nightmare Circus is not a Souls-like game, we deliberately adopted one core philosophy from the genre, which is respecting the player’s intelligence.

Our bosses are not designed to feel random or unfair. Their attacks have weight, their movements have intention, and mistakes are punished, but fairly. When players fail, they usually understand why: poor positioning, overcommitment, or ignoring the surrounding space.

At the same time, we don’t ask players to win through precision alone. Bosses in Nightmare Circus leave room for creativity–using collisions, manipulating the stage, and turning momentum into advantage. The tension comes from pressure, not from unfair design, and the trial-and-error process must feel smooth and pleasant for everyone

Mini-bosses are where this philosophy begins to take shape.

In the demo, Mr. Kettlebell is designed to be direct, heavy, and honest. He embodies physicality and momentum as a character. His powerful swings, readable attacks, and constant spacing pressure reinforce a single lesson: your movement matters.

If players are still unsure of their movement, positioning, or timing, Mr. Kettlebell applies immediate pressure. But once players understand when to engage, when to retreat, and how to control space, the fight becomes readable.

Defeating him is not about finding shortcuts, but it’s about truly mastering the fundamentals. Which is something you must know before proceeding through the next challenges awaiting you.

Victory over a mini-boss should not end with relief alone.

After defeating Mr. Kettlebell, players receive a new ability: Slingshot. This is not simply a new weapon–it is a reward for understanding. It tells the player:
“You’ve grasped the basics well enough. Now we trust you with a more powerful tool.”

This process ensures that you don't feel overwhelmed with many tools at once, but rather learning progressively and feel confident with a few mechanics first, so that you can move on and master the next kit item that you will use throughout your adventure.

Another main principle that guides all of our boss's design is that we avoid explicit instruction.

We don’t want to tell players what to do since that would go against the idea of respecting the users’ intelligence, besides stripping you of the satisfaction and pride to understand and overcome the challenge without external support.

Bosses: Testing True Mastery

The final demo boss, Strongman, elevates everything further.

Visually, he represents dominance and control. His mass, posture, and animations communicate crushing pressure. Mechanically, his purpose is singular: to test how well the player can use Slingshot.

Strongman does not demand faster reactions. He demands understanding of momentum, angles, and collision timing.

If Slingshot is used hesitantly, the fight becomes oppressive and exhausting. But when players begin to use it with confidence and intent, the fight opens up.
This is the first big leap the players will have to take to move on, since the Slingshot is a core mechanic in Nightmare Circus, we added extra emphasis to make sure that you become fully aware of its potential and use case scenarios.
And the proof that you learned is defeating the Strongman

This dev diary only scratches the surface of our boss's design philosophy.

In the next update, we’ll be sharing announcements about Steam Next Fest,
along with a changelog for the upcoming demo version, directly shaped by player feedback.

The circus continues to evolve.
And the next performance… is about to begin!

The story of Nightmare Circus began as a simple idea: a small troupe of traveling circus performers who, unfortunately, strayed into the wrong place and found themselves trapped in a nightmare. From the beginning, we knew that we wanted Nightmare Circus to have a story that would integrate with Peppin’s journey throughout the game, visually and mechanically.
From the base idea of just defeating bosses, saving our friends, and escaping the nightmare, we worked on expanding the story, using each troupe member’s fears and personality to build upon each world and its mechanics, hoping to give more prominence and importance to each battle Peppin faces and the bonds between him and his friends.

To create a sense of immersion between gameplay and story, we created Nightmare Circus’s environmental storytelling system: aspects of the story are woven throughout the worlds, allowing for exploration while keeping the overall story understandable in easily digestible segments. As the player journeys through each world, they will see decorations and items throughout their surroundings, designed to give clues about the personality, fears, and characteristics of the troupe member that each world is based on.
Since the game is told through the eyes of Peppin, each world was designed to have an overarching puppet-like style, befitting of our protagonist’s preferences and identity. Scattered throughout the game are also diaries, notes, and objects that the player can discover to unlock even more lore of the world and each character on their own volition, allowing players the ability to explore Nightmare Circus’ story at their own pace and preferences.

This means that for those who will be more inclined to explore each level thoroughly, they will be rewarded with extra pieces of what is really happening in the Nightmare Realm.

In Nightmare Circus, we also decided to blend elements of the story into the gameplay mechanics. From the protagonist’s choice of weapon being a Puppeteer’s Control Bars and its unique abilities to the various skills he unlocks with the help of each of his friends.
Every fight is purposely designed to show each step of Peppin’s growth in character and his abilities as he learns more about himself, his companions, and the mysterious realm that traps them. To give purpose to each of Peppin’s skills and power-ups, we gave him the base weapon of a Control Bar, a familiar item that has been with him since his start as a puppeteer. Then, as Peppin grows stronger and can defeat more nightmares, he, in turn, receives assistance in reciprocation in the form of items and mysterious skills based on the personality and specialties of those he has helped, giving meaning and connection to the bonds built between Peppin and his friends, both old and new.

To further build on the story of Nightmare Circus and the world within the game (after all, it’s too much of a coincidence for the Nightmare Realm to exist without explanation), we introduced villagers as a tool for storytelling. Villagers are NPCs whom Peppin can meet throughout his journey, with each villager allowing Peppin to learn more information about the realm’s existence and origins.

As to what it is, you’ll have to play the game to find out!

The process of developing Nightmare Circus in the aspect of Storytelling has come with its own set of challenges. The balancing act between storytelling moments and gameplay is one that we must continuously adjust throughout the development process. On one hand, we want to tell as much of Nightmare Circus’ story as possible, ensuring that each part of the crafted lore makes it into the game; however, we also need to be mindful of how the story flows and is experienced through the unique playstyle of each gamer, as well as the feasibility and limitations of what can realistically be implemented into the game while maintaining the intended complexity of Nightmare Circus’ concept. All in all, it boils down to finding a delicate balance between fun gameplay that has a good combat experience and a straightforward yet engaging plot that players can enjoy.

Despite its seemingly straightforwardness, the story of Nightmare Circus has always been intended to be open to players’ interpretation; every person has their own experience with fears, uncertainty, and emotions, and while there is a story we want to tell, we also want the players to develop their own understanding of the story and the fears of each character, and their journey to overcome their nightmares. Ultimately, we want the player to craft their own connection to the story through Peppin’s eyes.

If you’re interested in exploring the realm of nightmares and taking on Peppin’s journey, good news! The demo for Nightmare Circus is available to try! We invite you to delve into the Nightmare Realm and experience the story of Nightmare Circus yourself. We hope that the demo will give you a taste of what’s to come in the full game, and if you want to uncover the full story of Nightmare Circus, please feel free to wishlist our game.

The circus awaits! 🎪
