I really like the mechanic of returning bullets to sender with a sword slash. It's a great way to utilize the theme, while also making the game a lot more fun. Other things that I liked are the creative health bars, interesting enemy designs, and just the fact that fairies are packing heat. As for critiques, I agree with a few things already said by singleshotgamer and CGpepper and I'm sure you're already aware of the bugs. I think bullet-hell and platforming can mix but the gameplay is a little slow for my taste. The jump is very floaty and the fairies too move very slowly through the air, taking it a while to maneuver both them and myself into the position I want for attacks. That is subjective though. You may, for example, prefer the slower and more methodical gameplay. I also think the audio mixing could be tweaked. The sound effects of the gun fire are really loud compared to all the other audio so it's jarring.
