Apple Jam is set in a jam factory infested with rats.
The display shows an overhead conveyor along which large helpings
of apples come at irregular intervals.
The aim is to move a man to catch and swallow these as they fall off the
end of the conveyor, else they fall through into the cellar where the
rats get them.
With every mouthful, the man, or the rats, get bigger.
The man has two hazards. Overeating can damage his health, but he can
nip into a thoughtfully provided sauna to shed some pounds.
The second danger is the rats which comes up to his level and will kill
him if they can. He can escape them by hiding in a lift until they have
gone by.
The apples keep dropping meanwhile, however, so the rats go on growing.
If he dies, an ambulance removes him - a delightful scene the first time or
two, but very tedious when often repeated since it greatly slows up the
real action.
The instructions on-screen are simple but adequate. I liked the option to
re-allocate the control keys to suit your taste of joystick too.
