Cataball

ardade game for Commodore 64, 1987

------------------------------------------------------------------------------
The player controls four bouncing balls that must make their way through
twelve environments ranging from park to desert and beach to undersea world,
collecting up to ten balloons in each. Each one of the balls must deal with
several hazards, by jumping over them or crushing them. Collision with any of
these will cause a ball to burst.

The player can speed up or slow down the balls, or control their height, to
make it easy to avoid these hazards. If all four balls have been punctured,
the player loses a life. Once all ten balloons have been collected, the
player is transported to the next environment, and when they have managed to
get through all twelve environments, the player is transported back to the
first environment.
