In what way does your game fit the theme?
The core mechanic of the game is the ability for the player to create at any given moment a rewind point that stores location and momentum, and being able to rewind to that in certain situations.
Moreover, the way you solve the puzzles is, in a way, thinking in reverse, since you have to picture in your head the way you are going to go about the problem and rewind that possible solution, from end to start

Did you write most of the code yourself and made all the assets from scratch?
Yes, all the assets we used, from code, to sprites, to music, are made by the credited people of the team, except for fonts and sound effect, which are also credited in the description
