Hey nice! You keep updating it, right? Because at some point this week suddenly level 2 felt more balanced. I am now at Level 5, almost out of powerups to choose from and a few new ones popped up. Nice!
Yep, I've been slowly updating the game and trying to balance it, there will be more and more upgrades added over the next week or two as I prepare the game for the steam release. Hope you enjoy the the content :)
