okay
you pick the begining plane, and go to this place, and shoot the hell out of helicopters and tanks,some drop 'items' (power boosters, for better attack) then tehre is a boss. you get $ per kill, if you kill the boss (you wont) you go on to this other level (different backround and planes and boss) and then you die. and you have 3 lives per game and 3 games.and if you have 250k$ you buy the second plane or save for the 300k$ plane. and each plane has specials. like the first one you an buy like a spell, that shoots in a circle around you. It cost 3,000 and you can use 3 times, if you die you loose it
anyway there are like 15 uniqueish levels. and you can earn more lives.
that was unorganized.
anyway I like it as much as super mario world, but its frustrating at times.
