The graphics are pretty awesomesauce. The only graphical thing I might suggest tweaking is to have the machine gun bullets leave a trail as they're being fired out showing their trajectory, but more importantly the biggest thing the game needs is some music and sound. The gameplay was ok but got repetitive quickly; if there are more enemies and challenges to unlock as you get further into the game then maybe I'll come back and try to get more into it, but only if it's updated so it saves progress. Also, a very minor note: when I play for the first time the mouse arrow still shows up along with the reticule and it only goes away after I die and then relauch, so it might need another FlxG.mouse.visible = false; somewhere.
