Solipskier

Now this is FUN! Instead of you controlling a skier racing against the terrain and performing stunts, you get to draw the terrain for the skier! This might sound boring after a couple of mins, that's why the game introduces goals like a specific area appearing where your guy has to pass through, or perform jumps, or tunnels etc.

Full marks! This is addictive as hell - I'm off to have another go :D
