The idea came from a bar game I saw a long time ago where you tossed a monkey into the air and then timed a button press to make a clown wack it with a club sending it flying across the circus tent.
It would slide bounce and continue on until it ran out of speed or hit something solid. The idea to see how far you could get, with various objects that would help you or hurt you in your distance.
The initial idea was that a manatee being fed up with speeding boats decided to place a ramp trap in the river. He would then trigger it on speeding boats giving them a wild ride down the river.
The rest of the river was then to be made of of various obstacles some helping some not. Right now there are just ramps and docks.
These games were really to try and make something fun as well as explore the physics simulation in Unity. All the boat, ramp and dock collisions are physics based as well as the initial acceleration and following decelerations.
Press space-bar to raise the launch ramp. Its right there at the very beginning. Then just enjoy the ride.
In version two I switched it around a little in that the manatee decides to steal a boat and take it for a joy ride. Again the same basic game play applies except in this version you can control the pitch of the boat.
The same space-bar launch button works and the up and down arrow controls the pitch. I had also changed the camera angle so the ramps are not visible anymore, but they are there.
