Did your son have a go yet slam? My daughter loves it and can't wait to get home home, saying that though she said the other two she thinks are better and this reminds her of other games with flappy elements, but that doesn't mean she doesn't like this and she loves the speed run part of it. Coins are generous and she's looking forward to buying all the custom options. First thing she said before loading the game " that Andy dude will be top" haha. She leaves me in her dust on twitchy type games now so she's going after Andy lol. She said she would give the game five out if five so that's what I've rated it.
