Neat little game! I would have loved for the gravity to be stronger as that would have made the inversions feel more snappy. Also I would suggest having fewer mechanics in play, since it’s a side-scroller, make the player auto-run. Then stick to the main mechanics which are gravity inversion, slide and breaking barriers. I’d also remove the slowdown from sliding as that came a bit in the way of my enjoyment of the movement. That one mode in geometry-dash but with an attack button and slides—essentially. As for the sound, the music was great! The art communicated the game well. Work a bit to simplify the cracked texture so it has no isolated empty pixels on the inside of the sprite.
