Fun little idea, but it needs more: Depth, Goals, items, something.

It's a very simple game. I don't understand why you have to press V, B, or N instead of actually clicking on them, and then going right into the game using the mouse.
The colors (Gold 'n' Blue) really are nice colors. I like the ship, but I think the blue dude should be a ship also.
The hit testing is quite off. Consider fixing (Or redoing that). It gets a little annoying. It's like you have to aim below the coin to collect it.
The text is fine, but it's small and hard to read.
I love the moving background. :)
I would also recommend adding music and sound effects.
Also, where's the title screen?

Overall it has potential, but needs some touching up and tweaking.

Not a bad game, but very simple and not explained very well
