A really neat little game. I remember seeing this on GMTK's stream, so seeing it in the Post Jam Productions server was a nice surprise. It's very well made, and I think it's one of the better designed puzzle games of the jam. Reminds me a bit of the ReThink series. I also had the framerate issues the previous comment mentioned, though I'm not entirely sure why (I had assumed it was a high refresh rate monitor thing, but now I'm not sure). I also found the controls for rotating to be awkward, and I feel like there should be a better solution. Still, I had fun with this game.
Also, are we playing as a child? The camera height compared to things like the tables and shelves seems really low, which makes me feel like I'm either really short or a child in this game.
