Hahaha, that was the most random thing I have seen today :)
Im not sure how everyone feels about the artwork but I liked it. I felt the game was a little unfair at times, i would jump the oil only to be run over when i landed, or i would jump the car only for the plane to swoop down and hit me.
I liked the menus, your map looks good. Ide love to see an intro to find out why this kangaroo is so hated!
