This game is charming. It has pretty sprites and a cute soundtrack.
It's a decent platformer. It was a little confusing that the first NPC in the game is friendly, only to not be friendly later. Same thing with the rat enemy showing up in the platforming section before being an enemy later. Felt like a cheap death trying to reach what was previously an ally only to be met with a bullet without an explanation.
The soundtrack is a chiptune version of "I'm Just Your Problem" featured in Adventure Time. It's a good cover, but it felt kinda like it was put in there without knowledge of it being a well known song. The only credit for the song itself is outside of the game. That felt a little weird, but it might just be me.
It also probably needed a level select since two of the achievements (Full Score & Pacifist) are level specific rather than accumulative like the others. All in all, it's a good LD game.
