Zipman 3 (no idea if episodes 1-2 ever were released) has the germ of a good game (decent sprite-based graphics and presentation) but some technical problems hamper it a bit. Your tiny character controls a bit erratically, as does the camera which does not scroll smoothly as you move forward. Those problems, combined with the "one hit game over" problem (as in start the whole GAME over, not just the level) cause this one to be an intriguing but unfulfilling game.
