There is a glitch where you continue to get money if you land on the ground and ignore the count down that would normally end the game by holding right or left, and clicking out of the game, so it continues to move slowly in that direction. This does not earn a lot of money fast, but it might be something to fix. Great game by the way =)
This was a fun game in the begining, until Kong would not give me the hard achivement. Kong needs to accept previous score, or at least be able to report missing achievement. otherwise great game
