day 3 - can you flow on snow?

Since I was too lazy to change my shader to look like flowing water... you are now flowing on snow. Which has some red color you should avoid. Which in turn leads to a bit of gameplay! If I have time (haha, as if) I can make multiple levels with different types of heightmaps. Also, I'm having fun right now trying to get multiple of the purple wizards to the goal so maybe this will be final gameplay - multitask to guide several of them to flow down the snowy mountain safely. Or I might go back to the initial idea and have the other snow-raft-riders be AI control trying to beat you.
