I cant rate (didnt submit a game for the jam :P ), but I loved this game, the controls are a bit hard to get used to. but with some better controls I would love to see this as a full game! I especially liked the 5 buttons puzzle and the last one, really nice ones!
The mechanics themself are really cool, and a really nice progression and difficulty curve! would love to see more mechanics than just cubes :D
I also made a quick playthrough, its unlisted: https://www.youtube.com/watch?v=2Q_i_PCALFQ
