Very cool rendering techniques. I found the levels where the eye chases you most interesting. The level where the fireballs come at you, while very cool conceptually, I found it a bit hard to judge depth, and the fireballs felt too easy to hit, like their hitbox was too big. I had so many attempts at the level that I started to see an optical illusion afterwards where the screen kept going inwards, but alas, I could not finish it.
