anyone that says more than 12 it literally has a cps tracker which is pretty much a counter for clicks because it says the amount of clicks done so use your brain
To the people who are saying "I BEAT IT IN 6 CLICKS!" The first UFO deserves more clicks and the last wave is 3 clicks So stop lying everyone and tell the truth
13, I count holding at the start as a click, stay mad edit: wow I get a lot more replies when I put insults in my comments edit 2: its been 8 months and I no longer care about this game (still counting 13 though)
