I got overwhelmed once the difficulty increased. Pretty cool concept with both directions and color mattering. Might make for an interesting rhythm game if synced to the music. That being said, I'm a bit on the fence about the correct color not matching the color of the projectile: the added difficulty of the color system makes the game more difficult to pick up, but wouldn't really add any difficulty once a player has internalized the system. It basically does the opposite of what you probably want from your difficulty curve. It's not necessarily a big deal, though, it doesn't matter much for a jam game of this scope. The animation is cute and Star is precious.
