Do-Do

Do-Do is a rather slow-paced clone of Sega’s Pengo. You’re a man in the
middle of a screen filled with blocks, and with enemies approaching you from
all directions. Your only way to take out the enemies is to push the blocks at
them, thereby crushing them. The nasties are able to crush blocks which are
not moving, though, so that you must hurry so as not to run out of blocks to
use either as a weapon or a cover.
