I'm very intrigued by how you programmed this. There's an "Antichamber" feel to it (I don't know if you know that game).

I really like the idea of trying to understand the environment through negative spaces. I must confess that after a while I had to press G a lot to get my bearings. The concept is cool and deserves much more than 3 hours to be fully exploited.

I really enjoyed the concept of the game,  and the mechanic has a lot of potential. But I don't see how this fits the theme. Overall really enjoyed , cool experience.
