not bad
Ive got similar complaints as everyone else
it could really use a save feature so you don't get to the third beacon and realize the new "energy chugging laser" doesn't become as much of a problem because you can load and change your style of fighting to adapt to the loss of energy efficiency.
if that doesn't sound like a good idea simply make the laser take less power to use, it may be overly powerful, but isn't that really the idea of upgrading systems that the heavily upgraded or maxed out guns make the game almost to easy?
also you could have always set it so you can switch to the laser by pressing 5 rather then it replacing our old guns.
anyway,
gameplay = smooth and quite fun (until you die and have to start over)
graphics = sure everything's black with a bit of color added in places but it gives you the feeling of a massive fight with lots of bugs = not the best but fulfill the purpose well
sound = below average = music was okay at death and there wasn't anything but some kind of white noise in game, nothing real special about any of the other sounds
overall = 7.5 = could use improvements but you on your way
