I loved the audio and graphics, it's got a really nice vibe to it. One thing that did irk me a bit though was the controls feel a bit unintuitive.
Personally I feel like your game would shine alot more if you could use WASD or the arrow keys and not press the onscreen arrows as they move with the camera which causes the movement to stop as the camera moves the buttons away from your mouse. Plus with the button to move down being above the move up button I kept moving down when I meant to move up and vice versa.
The game seems really nice it was just hard for me to move past that. Great job anyway with it all!! I don't want my criticisms to outshine the fact I think you did a good job.
