I haven't played it either
I could still, however, enjoy how cool and funny this cartoon turned out to be. It was hard to understand some of the jokes but the good tone and animation negates that. It was weird to see them use the roller coaster at the end when they seemed to have no metal cart to go in. Then again, I guess they didn't have any metal to use in the first place? The zombies look like cactuses shaped like dildos! The funniest bit of it was probably when he was talking about stepping deep in seriousness.
