Same here. Also, such games would certainly benefit from single-hand operation in mind. I'd prefer UP for rotation, DOWN for drop, and, maybe, PgUP/DN for L/R r

Same here. Also, such games would certainly benefit from single-hand operation in mind. I'd prefer UP for rotation, DOWN for drop, and, maybe, PgUP/DN for L/R rotation, END for hold. And similarly on the WASD side of the keyboard, so either hand may be used optionally. Or even for one-keyboard multiplayer. )
