This is a puzzle game. So, why the minigames are so difficult?
There's a bug with gravity: When you jump with the gravity off and immediately turn it on, you can do a "Tinky Winky Jump"(A very high jump) and jump parts of the game.
When you go to the upper way and fail the long jump, you can enter the minigame that you expect that is only available when the player cross out the rule "The player can't stop time outside rooms".
Why don't make sound effects and music?
When you fail a challenge is very annoying to go where you were before. Why you don't make the map a little bit smaller or make the player faster outside rooms? Why not both?
I see future in this project. :) Very original. I enjoyed so much.
