Very cool! Loved the low res textures and sprite work, and the dungeons have a really nice atmosphere.
Super impressed with the level design and that you were able to implement walking on walls. The extra dimension to navigating the dungeon is a cool feature. The rune swap in/out to manage your stats was a neat mechanic too.
I noticed the whole game was squished and the pixels weren't square, likely because I was playing on a 16:10 laptop display instead of 16:9, but thought I should mention in case you're planning to add any optimisation updates in future.
