I recently reviewed a game called Little Gang, also for the FM-7, which was a clone of Mappy. This is a clone of Pengo. It's pretty good, they didn't seem to skip on much detail. You can still get the Snowbees while they're in the ice blocks, you can still get a big bonus for lining up the three special blocks without using a wall (or a smaller bonus if you have to use a wall), and you can still kick the wall to cause a vibration that stuns any Snowbees that are hanging around by that wall. Solid!

And the cover art is nicely done, too!
