I'm going to have logs going from one side of the stream to another, where the player will need to jump between the moving logs to get to the other side. If they miss jump they fall in the water and get washed down stream.
Well on that case, it looks simple to me. Just create the moving platforms going from one side to another. Combine with my Jump System plugin to allow player to jump on platforms. If they miss the jump, they will fall under the hole region.
