Really fun game. You guys are aware of the bug where you half pick up a block and it moves with you but you can't place it anywhere? It throws you off a bit and losing track for a moment is death. Distracted me in my last two attempts. I'd definitely buy a version for a few bucks (or even just donate a few here) if you clean up that bug or add some new stuff. 

Saw someone play it in a gmtk compilation and it immediately stood out. Really cool, and fun to play as well.
