Number of playthroughs: 2.

Glitched achievements: None.

Missable Achievements: Many. Each one will be marked below.



Complete the game, making sure to craft every necessary item and find all notes.
Play through the game once to get familiar with the areas and what to do to progress. During this step also be sure to craft every single defensive item. If you don't craft these you will permanently lose a health bar per area making the game slightly harder to explore. While going through also be sure to grab every note and misc. achievement so you don't have to with reduced HP.


Replay the game without crafting any defensive items.
Now replay the game without crafting the taser, caltrops, etc. Every time you leave an area you will permanently lose a health bar. If you made a save to get both endings you will only need to play as far as the Gymnasium.

Lighter: F
Matches: T

• Try not to sprint too much and conserve stamina. This will be especially useful when you need to hide from or dodge enemies. There will also be times where you need to run from monsters and you don't want to get caught with your pants down.
  
• The only items I ever really needed were stamina items. I usually had 2 of them and 2 healing, as it's very easy to dodge enemies in this game.
  
• Whenever Song (or any other "boss" enemy) spawns in, they will give off a sound alert of them walking. Step into a side room, or if you get caught, lose line of sight then enter a hiding spot.
  
• Every single threat can be sprinted past or dodged. Bosses will require a dodge.
  
• Save often, especially when going for I'm Invincible!. There were about 3 or 4 times where I got caught off guard and insta-killed.
  
• This one isn't as useful, considering how many matches you can find, but you can prolong a single match for a very long time by activating one in front of a container you want to unlock, opening it, then quickly pressing F to pull out your lighter.

As soon as you arrive in the Gymnasium, there's a bit of prep work to do for a secret room in the Hospital.

About halfway through will be a new portal back to the hospital. Do you remember that blood covered door with a bunch of lights above it near the start of this area? Go there. Once inside, read every note, then exit.

Hospital bunker location












In order to earn these achievements you need to escape key areas without crafting their respective defense item. These include the Taser in the police station, the Caltrops in the Dokkaebi Market, the Gasmask in the subway, and finally the RC Car in the hospital. After each area you will permanently lose a health bar and must do all 4 in a single run. Note that going for I'm Invincible! will have you completing the Gymnasium with only 1 bar of health. It doesn't make the game any harder in my opinion, but I should point it out.
