As part of Jonathan's idea he suggested on Gamasutra to add visual cues or clues as to where to go I added some fireflies into the scene to give the players a hint. For instance on the middle deadly mud bog it would be perhaps logical for a lot of player to try and jump to the broken dock on the other side of the mud bog from the center island, and although it can be done it is a bit of a tricky jump. The safer jump is to the right of the dock along the mud bog edge. The fireflies flying around the glowing green fungus will hopefully provide a clue to the safer jump option.
Here we can see a screen capture of bud the spud with his very helpful Fireflies. They are an animated particle system so if you get close to them you can see a little animated glowing bug flapping its wings while they lazily fly about and fade in and out. It's awesome comments like those from Jonathan that I just love and REALLY take to heart. ;)
