just have some controls for shifting forward and backward and rotating the camera in 90 degree steps while bringing the piece with you, the falling piece still controls exactly like normal Tetris, but it rotates along with the camera rotating, it slides along the camera axis changes, and the camera plane always aligns with one row of the 3d stack, did I miss something or is this not the obvious approach? the adjacent block rows can become more translucent but maintain wireframe the further away from the focus row, etc
