+  <p>
+   Control a worm in its quest to eat bonuses and become longer. Outmanuever
+   enemy worms while eating doughnuts and ice cream to increase your length.
+   Each worm has ten lives and loses one by running into a wall or another worm.
+   The enemy worms are after the same bonuses that you are, so be careful: if
+   they become too large, you won't have much room to manuever.
+  </p>
+  <p>
+   The adventure progresses through 26 maps of increasing difficulty. The early
+   levels are mostly open with a few walls, but later on, cramped spaces and
+   teleporters make things more interesting.
+  </p>
+  <p>
+   Play on your own against up to five enemy worms, or share your keyboard to
+   let one or more friends join the fun.
+  </p>
