You've got a cool game! Nice graphics. Nice animation. Satisfies the theme of jam.
If you press R before the first checkpoint, then you appear outside the maze. If you come to the first purple chest without a key. The camera moves to the door then to the void. And it's not clear what is required of you. I stood and jumped on the chest for a long time. Trying to figure out what to do.
The game lacks sounds for the atmosphere. During the shaking of the screen at the end of the game, my kettle boiled. This sound has greatly increased the atmosphere! : D
Overall, the game is cool!
