Needs work.
Okay, the gameplay itself isn't the problem. It's the "WHAT THE FUCK IS THIS AND WHAT DOES IT DO?" problem. Perks that give me NO CLUE what they really mean (+ damage for certain guns, BUT WHAT WHICH GUNS? I have no clue what gun is what!) or they're too useless. +2% critical chance? Pffft.
I kept wasting perks because I'd spent one on a damage drone, then get a repair drone, and then back to the other drone. It makes me use a perk point but doesn't refund any for replacing the other drone. Crap.
The weapons weren't overpowering and didn't have that "this is best" feel, which is great. However, again, the perks that pertain to the earlier weaponry is useless to get, since you get a much better upgrade later on that makes the perk associated with that weapon meaningless.
Okay, what's the point of the game? Killing? I mean, you go from one planet, kill bugs, then on to some ice planet, then some lava planet, and blow that one up. Then you move to a machine planet. What's the purpose? GRAAAAH! The game is like a hair knot. It makes no sense why it's there, but you really, really want to find out why. You know?
Thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, thank you, for not selling out to MochiGames and making some premium bullshit for sale. We all know MochiGames is the Lord of Faggotry and is the cancer that's killing flash games, and I want to expressly thank you for making a game that doesn't make me want to sink my heel through the monitor, because some unobtainable powerup is only available through those gay coins.
Lastly, the game is too easy. The lava part with the little dicks shooting peas at me was the worst part, but I didn't ever have much trouble anywhere else in the game. The bosses were meh, cool-looking but otherwise speedbumps in my quest to kill and dominate everything.
