Amazing game! The concept is very good and it's used in very clever ways. The level progression is very well done, introducing new concepts gradually in every level. The way the information is presented is very cool as well and the game overall looks and feels FANTASTIC. Only minor gripe is that the cube could move a bit faster...and that the button you leave on the floor should be shown, I was stumped in a puzzle for a bit until I realized teh button markings on the floor don't update if you leave a different one.
I wish there were more levels, but I know that with the limited time of the jam it's very hard to make enough content. At least the game had a beginning and an end, which made it feel very polished.
Awesome job, my #1 pick to win for now :)
