It's a fun game, though it is a little repetitive. I would have liked to see more levels, or maybe more hazards as the game progressed. I think one thing you could have done is added a longer bridge and scattered treasure throughout the bridge. Another thing you could do is add in a jump command and create more hazards that would require you to jump to get around them.
The presentation and the graphics look really good though, and I also like how you added a leaderboard. Nice job overall!
