A very nice flying simulator and it is fun to be the bee. The overall environment was fun to navigate. At first I found some of the perspective camera distortion when accelerating or close to objects to be unwanted, however, I began to feel like this was a bee's-eye-view and their lens into the world could be quite different. The camera could have maybe been a little closer so the bee wasn't accelerating so far away from the player.
I think the game would have come to life more with more ambient music and sounds. I agree with the many comments about preferring WASD controls...but here is why...players generally have left hand on arrows while right hand controls the camera/player view. The left hand needs to frequently move over to space bar to take flight after landing. This is just a bit jarring because it doesn't feel fluid. The initial screen options of Restart and Resume felt confusing since we were just loading into the game for the first time.
Very nice idea and work in 3D space. Was worth playing to fly around.
