For about two minutes I fell in love with this.<p>And then someone started repeatedly stacking blocks in any game I played to force a loss. And there was nothing I could do. Me and my teammates' beautiful castles of tetra...destroyed.<p>Find a way to fix that, and you have an amazing game on your hands. <3 it.<p>---<p>EDIT:<p>So after playing a little more, and getting more acquainted with the game, I can add that I love the dynamic that multiplayer adds to it--especially when you have six or seven other players and you're all trying to space yourselves out evenly, and you sometimes have to cross the whole map, putting pieces in and fitting them around with other people--I had some people do some (incredibly good) anticipation of my moves and vice versa--it felt surprisingly cohesive as a team game for something that used to be such an individual effort.<p>I have a note about the IP of Tetris, because I seem to recall reading that they're: 1) quite strict about the licensing of the game and 2) adamant about the rules and structure of the game when they do give permission for it to be used.<p>I love Metris, and for a 48 hour project I think it's awesome--I also second the feedback given by Jarred, particularly for ghost blocks where my tetra-block will land, and the movement: holding down keys.
