This game is absolutely beautiful, the background animation is mesmerizing and the scratchy lofi style is just wonderful. After level 20 the game starts to get a little out of control as you scale up way bigger than the enemies can, but it's an astounding proof of concept. If this game was developed just a little bit more, with some enemy variety and some more upgrade options I could absolutely see this going for $5-$15 on Steam. Amazing work!
