Ice Master

Ice Master is another early Pengo clone. Your small man runs around in a
landscape filled with blocks of ice and populated by insects. Your only goal
is to crush the insects by pushing ice blocks at them. You can only push one
block at a time. Trying to push a block that is blocked by another block will
instead destroy the block so that you can push the one behind it. All insects
must be crushed before you can go on to the next level, which is made more
difficult by the fact that they respawn, so killing all in a quick succession
is required. Bonus score is calculated based on how much time is used. The
game runs in black and white high resolution mode, with artifact colour on
NTSC machines.
