Love it! such an endearing concept with some good tunes and fun gameplay. I loved the progression in difficulty from stationary cacti to tumbleweeds and skunks. The only minor critique I would give is the pistol just seems weaker than the other two powers, especially by the later stages. But I still very much enjoyed the pistol so it's not necessarily a bad thing. Anyway, this was a blast I really enjoyed it.
Good stuff :)
