Tetris on a futuristic (mainly but not only) topics, where each level has a certain conventional narrative justification (say, to fill the spacecraft energy), unusual (and always different) design pieces that fall from above (forget about the "boring" blocks and get ready for the real pretzels!), and indeed very original and beautiful level design.
On the other hand, despite this schedule, as it is the game this thing is not particularly original: in fact it's just another version of Tetris, which will be of interest primarily to fans of the various "ideas" on this subject.
