Nice work on this game. For starters, I really liked your music and sound effects. I paused on the start screen just to listen to the music, and I loved the Twin Peaks Intro/Theme vibes on the reawakening. The sound effects were also great -- I actually got a shiver when the creature ran from side to side near the end. You used a limited world but did the art for the world well -- the matching screen was really nice, and the warping and mid-warp exteriors were very cool.
I didn't read any comments on the game until after I finished it, so I thought it would be useful feedback for you to know that I did figure out how to solve the puzzle (without guessing) after the shutter failed.
Nice job on this!
