At first I was going to pass this one by. You aren't being shy about it being a flappy bird clone. I ended up deciding to give it a try. Got through a few towers and then stopped thinking "It is what it says on the tin". As I scrolled down I to comment I saw: "A flappy bird clone with a witch who can teleport." that stopped me and I went back to figure out the teleport. With the teleport you've got a little more of a game here. I think the theme is a little forced but I think you could mess around a bit and find something flappy bird but more interesting. Your Icon for the teleport just made me think it was saying left click to use the broom to do the flappy bird bounce. It's lucky i caught the teleport comment.
thanks for the game!
