Can tell a fair bit of effort went into this, just from the opening. It has a lot going for it. The plot intrigues.
Would recommend keeping the important controls listed somewhere visible as a reminder. And letting the player sprite have a little more animation, like blinking or rolling sometimes; would be nice. Not sure how big the game is usually supposed to be, but in the newgrounds window the text was a bit small and hard to read.
Visuals are charming, and the little effects are quite nice. Overall, it's got heart. Hope you continue on it.
