I think this was a neat project! The platforming felt very tight, the shooting felt satisfying (although the enemies could have more of a satisfying effect upon death), and the level wasn't too hard. Well, let me rephrase that. The individual level segments and challenges aren't too hard, but when you combine them without checkpoints it gets tough! I kept getting stuck on the way back after activating the blowers, where I needed to do my first horizontal jump. That kinda felt bad and after a lot of tries I unfortunately gave up. So checkpoints would be super appreciated! Also, I think the boss enemy could be a little more difficult to kill. I was really surprised when he only took a few hits, hehe. Other than those two things I think you did a really great job. Nice animations and sprites! Fun story and unique mechanics in my opinion. With a little tweaking this could be an even better game!
