Hey,
First of all - i love the choice of colors :) that type of Orange goes very well with black, everything UI wise was very good and well organized.
I tried it for like 10 mins but its quite hard to play, is the movement supposed to be this fast? is it possible u didn't make it frame rate in-dependent? it just flys by.
in addition, after u get hit there are like 3-4 seconds u cant shoot, thats a lot of time.
Dont get me wrong, i've enjoyed it but it needs more juice like firing and hitting SFX, some particles for explosion, and reducing the time you can attack after u can get hit, lots of potential here!
keep up the good work!
