Potential hampered by poor controls.
This game could have been something. It's rare you see 3D work of any quality at all here, and this accomplishes that pretty well. The controls are just painful to use on at least two counts, though: One, that your chopper will only move in one of four directions. The lack of diagonals is a huge problem when strafing while maneuvering is a vital part of avoiding enemy fire, which it is in this game. Secondly, turning with mouse and keyboard controls seems smooth out of combat, but as soon as it targets an enemy it goes insanely jerky and I spend several seconds totally out of control as the auto-targetting fights with me. Your heart may have been in the right place with that feature but the implementation is awful.
Clean that up, and you might have something pretty good here.
