Cubic Tetris

Description
Cubic Tetris is a single-player 3D Tetris game, using similar rules to Welltris. Blocks fall down into a pit, and can be rotated in 6 directions and moved. A layer will be removed when there are no gaps, and a score will be given. The pit is shown in two views, with both visible at the same time: an isometric view, and a view from the top.
