There are NO missable achievements in this game.

If searching for a specific achievement, just use Ctrl + F on the page and search for that achievement.

This is a great game for achievement hunters IMO.
It has a great story to experience.
It has some hidden collectibles (but not too many) and some speedrunning-related achievements so it has a little of everything.

It should take you somewhere from 5 to 20 hours to fully complete.

In order to get all the achievements in the game you will have to play it at least 2 times.

I suggest on your first run to enjoy and play the game slowly.
Get the hang of it.
Learn the physics and the different ways of navigation.

In addition, I suggest playing the game on Hard mode the first time but it's not necessary.
If you choose to do that, when you complete the first playthrough you will get the Death Wish achievement and you may spare a replay or two.

It will take you somewhere in the range of 2 to 5 hours.

While doing this you will get the following achievements by following the story.

After you finish the main story of the game, you'll still be able to use your save.
From there, you will need to beat one additional boss (if you haven't already, but most likely you already have) and collect the remaining collectible items.

You'll need to beat the game at least one more time (maybe more) to get these achievements.
Before you start, read the whole section so you decide if and how are you gonna combine the runs.


One of these runs must be a speed run .
You need to complete the whole game in under 1 hour and 30 minutes.
In addition, you will need to get out of the spaceship in under 1 minute, beat the first boss in under 5, and collect 10 feathers in under 10.





In one of the runs, you must not die. That won't be hard if you choose to play on Easy mode.
You can combine this run with the Speedrun so you won't have to make 2 separate runs.
This way the Speedrun will also be easier because it will be more unlikely for you to die in boss battles.



Lastly, you will have to complete the game on Hard mode once.
You can theoretically combine this run with the Speedrun and the 0 deaths run but this will make the game a lot harder and you may not be able to complete the Speedrun because of deaths and retries.
So, instead, I suggest you combine the Hard mode run with your First run.
This will make the next achievements much easier for you because you'll be able to get from the hardest difficulty to the easiest.

• The teleports cannot be used until you beat the 3rd boss.
  
• The pictures are inaccessible until you reach the endgame.
