Hi guys! I've been working on the design of my Tetris clone game and some minor adjustments like adding hold and drop function. The design is a bit rough. I even forgot to have my power nap :D. I was having fun doing this. I would also like to share to you about vibrations on Android. It would be nice if the user can feel they clicked on something by adding a what they call "Haptic Feedback". So I added a vibrate function and add it in my game engine.
