"The more you have, the worse it is" principle can be applied to the most of classic arcade games. For example, Snake gets worse each time it grows another tile of it's tail, and Tetris gets worse with every tetrimino you place. Why not to just take this mechanics and combine it the funniest way you can?
Let me introduce: SnaketriS!
Snaketris is a hotseat cooperative game for two where the first player uses cursor keys to control snake, eat fruit and grow, and the second player tries to play tetris using WASD. Your aim is to clear as many lines as you can, just like in classic tetris game. With a little difference: you can use snake to do it.
How many points can you score?
