This game has a nice, quirky personality. I liked the music and the art, especially the main character's sprite!
I had fun even if I didn't manage to finish it!
I think there are a few places where clarity could have been a bit better, like in some parts of the level design (it felt like I sometimes couldn't go where it looked possible to traverse and then in one part of level 2 it felt like I was walking inside a wall) and some of the abilities, or projectile feedback. Not a huge deal, though!
The game crashed a few times, sometimes on start of the game (post intro), sometimes on death. Other than that, the only bug I encountered is that an enemy kept shooting after dying (one of the level 2 ones that shoot a line of projectiles).
Overall, I quite liked it, well done!
