This was a very interesting game. I loved your sprites, and the cinematic opening was very impressive! Music was really excellent too, however sometimes it would loop over itself really rough; it's hard to explain. It would like play two+ instances of itself at once sometimes and it was really chaotic! But switching rooms seemed to fix it. Only other nip pick I had was, at least that the beginning, the movement felt like a really weird mix of stiff but floaty. I got used to it though the longer I played.
Otherwise I had fun playing it! I did run into, what I think was a bug though that I found pretty funny. Right in the beginning area where the two first switches are, I could could jump into an open space and the game just ends lol. There's dialogue that talks about keys or something, but then it immediately transitions to "CONGRATULATIONS!" hahaha. I went back after doing that though and played the game for realsies ;P
Well done!
