Not the most original concept, but it's one that is executed fairly well. Killing off the hoards of enemies coming at you was pretty satisfying, and I think the different emotions having their own abilities was cool. The soft piano music was really nice to listen to while playing, and the sprites were simple yet somewhat charming at the same time. There does seem to be some sort of time limit or maximum score or something, though, which I felt was odd. I'm not really sure why it's there to begin with if I'm being completely honest. Overall, simple but solid. 7/10.
