Soild platformer overall! Personally I prefer checkpoints over the idea of multiple lives, making it frustrating when things like bugs and wonky collisions caused me to eat lives. The pixel art was very nice, but I really could've used some visual feedback when hitting a fairy because I kept assuming I was missing because of the slow and small bullets. Also it was a bit annoying how you'd reset immediately after dying, often making you not realize you die and you do an input that like, throws you off a cliff. A small delay would've been nice. The boss was fun but ate up the entire stock of my lives when she changed patterns because there wasn't much room to dodge the small dense bullet spread. Good ending screen though.

Hey, pretty tight platformer! I'd like to give the programmers the benefit of the doubt that the blue field around the level was meant to be a big collision zone that just didn't work because jumping out there let me skip parts of the level sometimes.  Being able to straight up jump past the exit door and fall down into the pit irked me a bit

Audio balance could use a bit of work just because the music was a bit quiet and the firing sound started becoming tedious in the boss battle. 

Art and animations check out as well, couldn't tell if there was supposed to be some text at the end, saw something for a sec and it blipped away.

There's a pretty nasty safezone in the boss battle though, its sorta on the platforms near the entrance.
