Very nice concept of a game! I really liked the retro art style and music. The idea of spikes turning to platforms using a sword that creates a glitch is genius, I enjoyed this game a lot :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
