Unlike I expected, it was't actually Flappy Bird, but more like a shoot 'em up without the shooting. I guess that's good, since there's only so much you can do with single button gameplay. Also, unlike I expected, the level isn't random, so the game is mostly about memorising the level. The game runs smoothly for a Unity game in a browser, and the important stuff, like the collision detection is mostly right, although some objects may have a bit too large hitbox.
