ExSheep is a Minesweeper clone, with a Tetris twist.
Instead of playing only one field, your game never stops, you can continue playing as long as you wish, more mines will come out from top.
You can check out SVN or use the 0.5 snapshot from downloads. It should run as-is via 'python esmain.py'. Please note that exsheep requires python-gtk2 package to be installed (It's installed by default at least on Ubuntu).
