Okay, I got assigned your game on the GMTK Reviewers Discord so let me expand on my earlier comment:
I like that the game does not operate on a grid based movement. It's way too much fun to aim your next movement to get exactly where you want. And there is a really interesting decision to make about aiming safer and scrape along the wall for a bit but loose time in the process or try to aim more acurately with the danger of overshooting in the wrong angle.
I also like the enemies that chase you. It's a lot of fun to lead them in the pits. :D
I'm not 100% sure how I feel about the damage mechanic. I think it might have been better if the spikes and the enemies would have been an insta-kill. I don't think that would have made the game more difficult because honestly, I don't remember being able to salvage a situation where I have been hit. And an insta-restart would maybe feel less like a wasted opportunity. However, that's not something really important.
What I would change however is the color of the "key" plate to open the doors. Them being the same color as the "change direction" plates means a bit of wasted time just searching for the things before trying to actually solve the level.
Apart from that the only other thing I can think of in terms of potential improvements is that the stone decals on the walls aren't completely transparent from the backside so you see some things floating in front of the camera when you look "out of" a wall.
All in all I stand by my point that this is a really fun game with a novel concept and overall nice graphics. :)
