Game has finish gg
It scared me when the numbers jumped from 10 to 100 before I upgraded the planet because that was starting to look like a whole lot of clicks... Thankfully the planet (moon?) unlocks helped make that a lot more manageable. Very thematic sound effects, and I enjoyed watching the moons orbit around the planet after being unlocked. Even if they seemed to disappear off the screen for a while sometimes.
I'd like to see some more depth in the upgrade paths or things you can upgrade to give the player some more choices and things to think about while mindlessly clicking.
