Call me a hater, but this game could do with a lot of improvements. For starters, it's impossible to avoid damage if the enemy has decided to shoot at you, you WILL get hit.
Second; controls, when I'm flying in circles looking for an enemy, I shouldn't get stuck going upwards when I change direction and having to let go of all buttons so it resets. Also, when trying to do a loop, the plane starts wobbling furiously, and the next moment you're upside-down headed sideways to hell, and the camera stays behind, always.
And to kill ships you have to go back to another lvl to find missiles, since they're next to impossible to kill only using the machinegun.
And if my maximum altitude and distance are set, why can the computer fly outside that? It's annoying to search desperately for an enemy when he's having scones above you or outside your fly-range.
This game has potential, and I'd look forward to try it again if some things get fixed.
