My eyes xD man that flashing background can be a pain on hard mode.
Fun, fun game, almost had me addicted to it :P Great idea to expand on, hope to see a similar release to this. Nice one button mechanic, although I do wonder what it would be like if it was a "left, right" arrow key control.
Very good, very fun, background is a bit harsh on the eyes, music is very good as well, Another cool piece of work from you sir. Hope to see more.
