You can't buy some of the upgrades without zooming out, which I didn't even know you could do at first. Other than that, it's a pretty standard, pretty fun incremental with, uh, quite the interesting theme.
Glad you liked it! You can also swipe to move around the upgrade panel. Thanks for playing!
Oh, I'm aware of that, but if you don't zoom out, you get stuck on the screen boundaries a bit too early. Thanks for your reply!
