Died at about 250 :) I thought it was a bit slow at the start, but it quickly gained pace! You've made a really nice balance. With more variety you could definitely expand on this :)
The sound effects are ridiculous, I love them :D
Nice Score!! I agree it could use more variation, I was thinking of adding different enemies that take more clicks to kill yet are slower :|
I also might add more decoration like rocks and cacti to make it look better.
