Fun, but needs balancing work.
The turrets are broken, for they shoot a bullet once the last one disapear (not at a fixed rate of fire).. so when they hit you at point blank they got something around 1500 rpm and kill you just like that.
The point system is flawed too.. you just must kill everything in a matter of seconds to get some points to buy expensive upgrades.. otherwise you get next to nothing if you are taking your time. (and you must, if you stop moving you are pretty much dead once you get to lvl4-5).
Change that to a good fixed reward per level, plus a nice bonus for speed and state of your ship.
Lower the cost for repair.. WAY too high. Maybe add shield regeneration.. Or add a "life" system so when you die you pop back up instead of starting from the beggining.
You should get a two seconds delay at the start of every round to get out of the way of the turrets.. i poped a couple of times right on top of them... and got killed in an instant. Not fun. Maybe add a "invincibility shield" that last 2 seconds at the beggining.. but prevent you from shooting so you dont die RIGHT at the start.
But i like the accuracy system.. nice touch. Did not try the wingmens.. but i guess they get killed all the time.. must see if my theory holds..
