I'll admit straight-up I was prepared to not like this, but it was lowkey some of the most fun I've had so far in this jam. You implemented a lot of different platformer mechanics and used them well in your level design, the movement feels intuitive and "right" in a way that a lot of platformers get wrong, and all of the levels feel like they were carefully designed to escalate the difficulty and present a variety of challenges without being too difficult. So great job! To really take it to the next level my small suggestion would be to spend some time in the future on giving more visual/audio feedback to the player, like particle effects and sound effects when the enemies die, screen shake, little things like that. Anyway, fun game, thanks!
