cool game bro! I liked the gravity effect a lot it felt very smooth to transition between up and down. The door animation at the end of the level and the attack animation were pretty cool. One small thing to fix would be the player currently floats a couple pixels above the platforms and it looks odd. I really liked the starry background, felt trippy. I would also recommend using a dedicated color palette (try Lospec to find some) because I liked the artwork but found the colors to be a bit too clashing. The player felt good to control too, nice work, keep it up!!
