Game has a great visual style. The controls feel good and the platforming was fun, with the minor gripe that falling sometimes results in tons of waiting around on enemies to move away, that leads more to frustration than a good challenge. There is a section where you have to double-jump and dash to the right to get higher up, and the last in this series was just a bit too far out of reach, which resulted in waiting and having to repeat a ton of stuff over and over. Difficult jumps are imo better made as a separate smaller section, so that redoing it after falling isn't as tedious. But overall, the difficulty feels balanced and the game feels fun to play.
The camera should be more ahead of the player, i.e. giving the player more space to see ahead. Vertically, the camera also cuts off just a bit too much, so that I can't tell if I'm jumping down to safety or to my death. Bit of polish there and some audio & enemy variation could really upgrade this to a great game.
