Presentation-wise, you did a very good job with the title screen, credits and overall look of the game. But there's one problem: HOW do you play it? I see you can use up/down arrows to move up and down, but what else? I tried pressing mouse keys, every single key on my keyboard and X360 gamepad, it didn't work, nothing happened, which kinda made the experience not that much fun.

Visually speaking, the game does look nice and has very good presentation, and the audio selection does fit it and give a nice mood, but it's a bit unplayable, aside from moving up and down. Some parallax would make the moving experience better on the game screen (backgrounds don't repeat and they're static) and variation on scenery would make it a bit more interesting.

I can see there was effort in building the game, and presenting it, and that's really good! But having it unplayable kinda missed the point. If it's a bug, and it's possible to fix it, please do so, so people won't have problems playing your game. :)

Good Luck!
