Woooah... With first arrow left/right the idea was absolutely sold to me! The most fun approach to the Tetris mechanic I've seen so far.
The whole "you can turn dices in 3 dimensions" idea is really cracking my brain (but only in a good way). Don't know if I am patient enough to truly master it, but someone definitely is and I can already imagine how much fun can be watching a skilled player running it.
Blast VFX, overall SFX, graphics and animations are soooo well done. It already looks like a AAA tetris game. Can't imagine how far it can go after the Jam. Amazing entry!
