Just found out about this game and it's becoming one of my favorites! Everything is really well done, love the feel of it, the graphics and all the options! I'm gonna have to buy it, I love it that much!
I did find (kind of) a bug: when pressing up to hard drop, if I press up and also lesft or right (sondiagonally), the piece hard drops a square to the left or right, not where I would like it. I play on Android with virtual keys so it's really easy to press diagonally. Could you maybe diaable diagonal touch?
