Fun game! Liked the parkour aspect and then blending it with a nice boss fight at the end. The gun only dealt 1 damage to a 100HP boss but I liked the time and the challenge. I liked your color palette to represent your 'layer of the mind'. Only gripe from me is I wish the death was faster and more animated, nothing happening when you touch the corruption you have to wait a few seconds to respawn, also plays a splash sound fx which doesn't seem fitting when you touch something glitchy.
