This is awesome! The mechanic is really interesting, and works wonderfully with the level design. Other than the rotate controls (maybe use e and q for clockwise/counter-clockwise? I kept forgetting which buttons I was using to rotate) and a few bugs that found me exploring inside the walls, I have no complaints. This is a really well polished, interesting game that on top of everything, manages to tell a nice story. I think this is my favorite game of the jam so far. Fantastic work!
