As a good rule of thumb; don't use more than three fonts in your game. A bit too simple to be engaging, perhaps aimed a very young audience - 3-4 year olds? The level should probably end when only bots remain - it's not much fun watching the game play itself. Some of the level art is a bit confusing; like thorny branches that do no damage. I appreciate the uplifting tone of this game, it was nice to play something cheerful.
