Thanks everyone, for the feedback and suggestions!

I'm really glad to hear that you've found it so compelling.
The only thing is it would be nice to be able to change directions in the air somehow. Or have places to perch in the upper area so you can switch direction by going up rather than down.
Great idea - maybe there could be giant airships above, or even a cave environment in addition to just pillars...
I would suggest adding some time honored game elements like possibility of losing and score (e.g. points are added for each second player is alive, randomly spawning extra life / score multiplier pick-ups, you lose a life and all multipliers on hit, you lose 1 (or 2, or x) multiplier level on perch).
Yeah, this was just a prototype to test out the controls. For the actual game, there will definitely be losing and score and all that. I was thinking of turning it into a side-scrolling game with a bigger playing area, maybe where you have to collect or deliver certain things between different places? And of course survive angry swarms and eat delicious prey animals and such...

I would love to be able to change directions, other than that great job, it feels right. I like the nose diving when you hold space

I tried one approach to changing directions in midair - that is, switching directions after a dive but it didn't feel right. I like Titch's suggestion about having objects in the air that you can perch on. I will try that.
YES this is quite rad!! I highly recommend finishing and submitting to Gamma IV
have you thought about being able to eat up the enemies by diving?
Thanks, I was thinking about Gamma IV, because the whole one-button thing.

Is it possible to detect Xbox 360 controller buttons with Flixel?

I was definitely thinking of making it possible to eat certain enemies, maybe even in groups of other fliers like dolphins herding swarms of mackerel... But I also like the idea of being able to attack by diving! Someone else also just suggested that to me, actually, and I think it could work really well.

I also got the suggestion that maybe you could be collecting food for your baby birds. I like that. I could go watch some
Planet Earth episodes for inspiration, maybe...
