Any one played with Aviary?

Came across Aviary yesterday and it’s really tugging me back to flash game dev instead of XNA…sigh.

seems a little rough on the edges but neat, none the less.

I already have a game concept I am going to fine tuen so this type of engine would be great.

If you have played with it… tell me what you think. If you know of other similar engines, let me know as well.

Thanks.
