Nice completing your 1st game! I thought the cat should have 9 lives, though. The ability to move the tank up like in centipede is a nice addition.
I don't know if it's a feature of a bug, but the border of Gaslandia and either Chuckleville or Straffon can be clicked for double fartbucks per click
Ya'll did pretty well with the role swapping. Visuals are good and bright. Music is pleasant with good sounds. Controls and runs well.
