Tetris...
Nothing new or original. Well, yes if you include the blurry shapes of the blocks and the chaotic random blast of colours once you remove the lines you've altered the concept. What we have here is all about a slight variation of the design.
The execution was alright though. Every next block lags a tad, maybe it was intended that way, I cannot tell. Decent game, try to come up with something original next time.
