Cool and original idea, but its very hrad. maybe i am just not true gamer but i cannot dodge and attack at same time. also z and x arent on every keyboard next to each other. 

This is a pretty cool idea but its pretty unforgiving. I found it pretty hard to actually get a collision with the blue orb and most of the time when I did I still took damage from it. The laser attacks are pretty cool but the warning is pretty short and in the later section where one goes off after the other I found that I often fell into the one I just thought I had dodged because it stuck around so long. All in all I think this is a pretty neat idea with a lot of room to improve one's skill.
