Wow this game feels very polished! The sound effects for the dice are well chosen to make the whole game feel gentle and relaxing, and I think you nailed this artstyle! My one feedback is that the red things were introduced too early in the game. Usually the player needs time to get used to something as strange as rotating a cube to face a certain way, so keeping it clear of obstacles for a while is usually a good idea.
Seriously though good job, this is a really neat and polished game that feels totally finished! If not for the length I'd have no idea this was made in only four days! Hats off to you sir.
If you have time in the next few days, come check out our game as well, I'd appreciate the feedback!
