A very simple and well made game! Incremental games are hard to make because it's all about the balance and the fun in restarting and going on and you managed to succeed at both! It was fun to slowly get stronger and stronger and just decimate all the enemies. My only feedback is that the start is very slow as it seems enemies get stuck on each other outside of the screen or just take very long to show up so before upgrading the enemy spawns, it can feel quite slow. Other than that, great work!
