Amazing game! It's low-stress, gorgeous, fun, beautful. I've never had so much fun flying around. In fact, I've never flown around before because I'm not a bird, but this game made me feel like I was flying. My one frustration was not being able to do a vertical loop, but then again, I don't really know if birds do those in real life. I can't wait to play it more. Amazingly, it looks gorgeous no matter what I play it on. On my Linux laptop, it's beautiful and performs great. On my Linux game machine, it's even MORE beautiful. I cannot praise this simple, poetic game enough.
