Fantastic idea! The idea and camera work were very appealing. The camera must have taken some time to properly configure. I made it to wave 5, but after that the invaders stopped spawning and I didn't obtain a win screen. Nevertheless, soaring about was enjoyable. Awesome game! Would you mind rating my game and leaving some comments if you have the time? If not, at least assist a few folks who fall under the "need for rating" category. You decide everything, so keep up the fantastic work, developer.
