Cute little game! With upgrades the gun does get overpowered but I also did a run only powering up the sword and it was quite satisfying to use. I did notice 2 bugs. First, I believe the little minions that the boss spawns don’t freeze during the upgrade screen. Second, I tried upgrading Knockback but it seemed to just upgrade one of my weapons instead. Aside from that, I really loved the pixel animation smears and the variety of robo enemies.
