Didn't like it.
The idea .. why not. But gameplay is horrible.
I think main problem is that the character is moving way too fast.
it's hard to control the movement. Evading one bulled but ran straight onto another one.
And: the window is way too big. You may use a laptop or flatscreen. But on a normal screen is doesn't fit in. You should use a smaller window.
As it is now, i can't give you a better rating.
