Also try the super fun game, Manhattan (romset: cmanhat) on Dataeast's DECO Cassette system
Tip: when starting the game and your guy drops, press button 2 to build up energy in the trampoline, and then button 1 to launch upwards
When falling down, for extra points: bounce off the points ledges on the side of the screen
after a little practice, one can get to the top of the building
