good graphics, good gameplay.. at first. once you get level 4 spread you dont get hit anymore if you can move in a circle and shoot behind you.
once you max lasers (not hard to do if you level evenly, favoring spread), i sat in the middle and moved my mouse in circles indefinately.
great game, very challenging, took me a while and think i cheated on the last round (check that the cannon shots clear the battleground before you can reenter, i lost and went back into the fight quick and a cannon shot that was half way there when i lost the last round hit immediately)
