As far as I know, there's only one Wii video game that
requires
you to keep absolutely still. You sit on the balance board
with
it's pressure sensors and if you move a candle goes out.
Kind
of boring.
The premise however is worthy of more exploration as
sitting
perfectly still for
minutes at a time is actually very hard to
master.
My proposal is to have the movement trigger something
more
devastating and to have the stuff on the screen try to make
you move. For instance, you roll slowly through a cave on
an
ore cart like Indiana Jones and snakes and spiders drop and
jump out at you. If you don't move, you're fine, but if you
twitch the slightest, they bite you and you die.
Hiding from the psycho killer or wild tiger would be pretty
scary. You could run on the board to get to a hiding place
but
once you are in a closed or behind the bush the slightest
movement gets you stabbed or eaten.
Not sure, this might have been done, but if not it could be
pretty fun.
