I didn't get it sorry. First the keys were not intuitive, I had to go back to see which keys to use.
The flashing was very disrupting.
The actual game play I didn't understand, basically you can't dodge between bullets and no matter how fast you move to the left you will die when the first bullet hits. No matter how much I shoot I don't see it having an effect on the enemy. I love the circular gyrus feel but at the moment I found that game to be frustrating and not in a good way. I hope that helps you to refine the game, looking forward to the next version.
