The concept is magnificent, you hit the theme spot on, there are sounds and they're great, the design is cool, and the level design is fire. Just need to improve the cube controls a bit—they feel a bit weird and grabbing them is kind of clunky—but for a 3-day jam, it's brilliant. Also, you should've added a restart before the beginning of a new room (but you already mentioned in a previous comment that you didn't have time for that). It turned out to be a very good game, I really enjoyed playing it.

Glad you liked it!
It's true, I had trouble making sure the player doesn't abuse the cube physics, that's why the reach is so low and collision is disabled when holding it, the lack of time does make it feel unpolished.
Speaking of time - as I said in a previous comment I wasn't even home on Friday, so my work started a day after the jam launched.
Thanks for playing and pointing out the issues!
