Inverted

What could ever be better than Tetris? Two Tetrises, of course! Inverted, "a new spin on Tetris", replaces the standard glass with a line in the middle, and tetrominoes of two colors, each corresponding to the other half's background. One tetromino falls towards the division line from above, another rises simultanously from the bottom. With every pair of tetrominoes, the area "hold" by each background color changes, until, as in ordinary Tetris, one tetromino exceeds the top, or in this case, the bottom, of the glass. Sounds complicated? It is not. Let me show you.

Both tetrominoes fall towards the border. The top one is controlled by the arrow keys, and the botton one by the ASDW-keys. When they hit the border, they modify the area of their background colors as follows:And, as mentioned above, you control this simultanously. It is not impossible, but I dare say ridiculously hard. If you are alone, that is. But then again, with a friend, you could as well play the other mode, which is versus mode. Compete with each other and see who will conquer the others "territory" first.

Another break from orthodoxy this time (however, the blog has now been officially revived - for the time being at least). No deletion of lines means no Tetris proper, but an amusing game none the less. Nice music, I might add. And you can play it for free, so you really have no reason not to.
