Funny Balloons tells the story of a kid that ventures in the wood and is kidnapped by
evil forces that imprison him in a mystic world. To escape and get back to home
he must play a strange game where he must guide balloons in different
allotments. Each allotments has a color and a particular points level. If the
balloon is driven in the allotment of the same color, the points are added to
the total score, otherwise subtracted. The objective of the game is to obtain a
value for total score equal to the target score.
The game is lost if the player scores a value higher than the target score or
overflows an allotment. An inter-level mini game allows the player to play a
slot machine game where he can win (or lose) points or abilities used in the
main game. The game features 12 levels of increasing difficulty.
