Interesting little game. The jumping controls are a little bit floaty, and It took me until needing to jump to the second jump upgrade to realize that i could jump after walking off of a ledge, you might want that explained to the player. Couldn't kill all the things in the end screen as they were stuck having a mosh pit on a platform below (reverted above?) me that I couldn't reach, so I hope there was no true ending unlocked by killing everything there, haha. Other than that, giving all the enemies that do different things a slightly different look would have definitely helped with the visuals.
