I got to, say, level 5, than gave up, as no new mechanics were introduced.
The intro is fantastic, especially the aztec chorus sound. Like the idea.
Would like to see - traps, walls you can push, some sort of a puzzle - i think it would fit the game nicely.
Also, a minor point, I would like to be able to rapidly press arrows, and not have the character not follow my commands in a timely fashion - simply put, more responsive controls.
I give it a 2.
