Excellent submission!
Minimal clicking required, most of the resource gain is either passively, or by moving the mouse. That's a huge plus! I'm so tired of the standard "click 100 times to unlock +1 resource/s"
I like that there's a complete game. I can play, and then reach a defined end rather than getting to some point where there's no more upgrades left and I'm left saying "I guess is as far as the developer got"
The art is simple, but completely sufficient.
