So, we've decided that there will be different "biomes", if you will, in our game that will benefit a specific animal that the player can transform into.  These include: highlands where the goat will travel faster, jungle where the tiger will travel faster (grass on track), and the cave where the rabbit will travel faster. I've already started on the cave and some environmental stuff for the jungle and highlands. Now I just need to do a cave that's turning and a cave that's splitting along with other plants and environments for the different areas.
