Really fun game. Liked the music, seems very original, really goes far with the theme. It's really satisfying to be interacting with my past version of myself like this. The level design is superb, I really don't have any gripes with this.
Okay actually I have one: The game also has a font as well as the triangle sprite, nd I consider fonts to be sprites. That's not enough to lose the five-star theme adherence though.
