Haha. Nice. Really strong and coherent theming and the art in general is quite epic. The music and sound effects help to create a really cool atmosphere and especially with all of the intentional glitches it's quite a unique game for sure.
My biggest advice to make this game even better would be to be a lot more generous with the collider sizes. It happened quite often that I got restarted even though I didn't hit anything, which feels a bit frustrating and unfair. Whenever in doubt about the collider sizes: Shape them to the advantage of the player. e.g. colliders of obstacles should be smaller and colliders of coins can be bigger. :D
Overall very well done. Excellent game and quite enjoyable to play. :)
