Online multiplayer co-op would rock.. I'd actually PAY for that. Otherwise the only improvement I could suggest would be the option of reconfiguring your weapon select keys. Good job!
A little too much momentum on the ship to be fun for me, impossible to make any kind of skilled halt if you're about to slam into something.. other than that I like it :P
Pretty addictive game. Need more upgrades, everything maxes out fairly quickly. Either that or make them more expensive so you don't have everything so soon. Kongregate high scores would be nice, too!
I want those 2 minutes of my life back :( Don't get me wrong, it's a fair effort, but I wish people would finish games before submitting them. You can't even try again without reloading the page :/
