Short and sweet Kirby clone. Nice controls and attacks, though the horizontal movement could be a lot faster. I like how you incorporated the kiss-your-partner-to-restore-health bit. Nice little touch. Marisa helping attack enemies is really cool, though it might've been a good idea to either give her more health or make her hitbox tiny-- she died and came back 3 times in the Rumia fight, and I couldn't do much to stop it.
In short, 'twas adorable.
