Minimal Tower Defense is a tower defense game (duh) where you
try to defeat waves of Blobs before they reach your tower. Of course, its less
of a tower and more of an orange-ish square on the right side of the screen, but
the idea stands.
Blobs appear on the purple square on the far left edge of the map, and try to
get to the yellow square on the right side of the map. Each time a Blob reaches
the yellow square, you lose one life. Lose all of your lives and it's Game Over.
