Awesome, I'm happy it clicked! Yeah for sure it gets repetitive, especially up to the later waves. My max was wave 50 where I instantly died, lol. I spiked the difficulty a little bit up there. I think if I were to continue this game I'd add more enemy types to vary things and some boss encounters where you have to shoot them with certain series of colors to kill them. Also more upgrades!! Stuff with synergy and anti-synergy, and maybe the ability to get some money to remove upgrades you don't want from the pool... So many ideas that I couldn't quite fit in haha. Thanks for playing though! :)
