I like the idea of playing drums on my mobile device, since my neighbours keep complaining about the sound a real drum setup makes. Though, right when you start the app you get this massive punch in your face : “WE WANT YOUR MONEY! “ me: nope, I just want to play this game. Game: get the free version then but you have to watch more ads then you even play the game so we still make a good amount of money anyways. Nice try guys, just try to be different and dare to stand out for once. Oh, and you should definitely add lessons, not just the 2sec tutorial. Cheers.
