rayvan is a fun Flappy Bird clone that has pretty much the same gameplay as its inspiration: the object is to get as far as possible by flying in the gaps between trees.
The hero of rayvan is, naturally, a bird, and he has a story, too: a dragon has stolen his egg.
Like in Flappy Bird, managing to get through more than five or six openings is a huge challenge. Playing rayvan may be as simple as tapping the screen to flap your wings, but you'll need to be very good if you expect to earn a decent score.
