A nice little game with decent level design. Music and sound effects are a good fit. It seems that you can't open the chests though (unless I'm missing something). Good effort.

An interesting little game.  It seemed pretty smooth, but I tried to open up the treasure chests and check the "!" sign with no success.

The game was cute. The gameplay was  little rough--particularly the collisions made it difficult to get some of the coins--and I walked right by the spikes several times without getting poked, which was unexpected. Also, you would get more people to play your game if you made a web export and not just a downloadable export. Overall, good job.
