Pressing restart always triggered a restart, even if it was pressing during the death animation. This lead to moments where I was waiting on a queue of restarts to each reset the character. On a similar note, I think restarting could've been quicker. I also would've liked the camera to always roughly center on the player, especially between different segments of the level, although I'm not sure if that would necessarily be a good change.
I thought the glitch mechanic itself was clean and well supported by the pixel art.
