Really cool entry I like the mood the game sets especially the tile art and opening set up. Character controller feels responsive however I'm so used to unlimited wall jumps I was trying to navigate the level not as intended at times but that not your game just my conditioning.
I can see lots of potential with this project and enjoyed my playthrough if there was one thing I would change it would be a little bit more global illumination. I can see where you was going and how it aid's with setting the mood but it was a little to dark for me as it stops me properly building a mental map between runs and causes me to squint a little bit to much.
