Awesome, thanks for the feedback! I agree, it is kind of pointless to upgrade after awhile, depending on which upgrades you chose, especially the Powerhouse or Ultrafast upgrades. With more time I could definitely have balanced it better
I actually did put in my "Nice to Haves" section that the Watchers would get bored after awhile, but I didn't have time to implement it. I also wanted to regrow the eyes so you couldn't mess around too long (which might add more to the upgrade system), but again: TIME. :D
