Interesting concept, and I like the sounds and art for the tiles! I also liked the audio cues that let the player know when the door was open, even if it wasn't in sight. However, while this feels like a puzzle game concept, many of the levels were focused less on solving some puzzle and more on just searching aimlessly for the levers or even the door. And with many of them off-screen, there was a lot of time spent searching, and then dying and needing to try again to get a valid path that works. I do like that there are many more tiles than just the ones needed for the puzzle though, it looks more natural, gives the player wiggle room for their movement, and doesn't reveal the solution too easily.
