Good ideas! But just a quick reminder that shift often triggers the sticky key so that could be a little problematic. And yet another vote for space; I'll surely change it. Ensuring frame rate is also a big issue, thanks for raising that too!
Oh you make a good point. Originally it was left/right mouse click. Then one of my friends said that laptops like macbook doesn't have right click button, so I changed like that. It's just two keys that you can easily be pressed with left hand (without moving your right hand off the mouse).
But I admit that it is not a very common choice. Is there any good alternative you can think of?
It's just amazing how this idea of double Tetris can add to the deepness of the game. Great design on details like constricting the rotation of blocks, which works perfectly.
