I so love this game. Reminded me a bit of "Lovely Planet" and "Clustertruck".
I have 2 points of criticism, tho:
1. To be honest, I expected the difficulty to spike at arround room 6, exept of the last 2 levels it was way to easy.
2. the music is placed inside the room somewere instead of being "inside the players head", right? This was quiet disorienting in a couple of levels and sounded really sh*tty. (which is so sad, because the choice of music was just perfect!)
Would pay ~15-20$ for a more fleshed out game with more and harder levels. This was way to short.
Any chance, you could add a .txt with direct links to all the music tracks? I searched on the soundcloud links given in the readme but haven't found all of them. But I waaaant them badly, because as I said: great choice of music!!
