Awwww yeah! This game just CONNECTED with me!
Simple graphics, BUT made juicy with some post processing and screen effects? Check!
Energetic soundtrack, and vibrant SFX? Check!
Enemy variety? Hell yeah!
BOSS FIGHT? There it is!
And then boss gets up, and you fight him once more? YEEAAAHH!
Seriously, the only thing I would pick on is that it's not very... loopy I guess?
Other than that, this is fire!
