basically you can upgrade the laser eyes until you get the 20k upgrade, and then it will show a 50k one, but don't try to get to it, because if you press it, it wont do anything cuz i didn't code that yet. Also, attacks happen randomly. And also lag can decrease kills. And in the shop for 35k kills you can get the rainbow token which explains it in the shop. Rainbow tokens only stay on the screen for 5 seconds. As of right now, they only give you about 6-8k every token pressed. I'm working on making it a random amount. also sometimes the exit button in the shop might be buggy sometimes, so if it doesnt exit out of the shop, just press it again. it should work.
everything made by me, made this kinda for my steam class but also as a game too
