Little Big Planet Stage

Everyone I'm sure has heard of Little Big Planet for the PS3. It's the side scrolling platformer that lets you create your own levels as well as play others. It's the youtube for gamers and it's been some of the most fun I've had in awhile. Today I'd like to show case a stage I have made as an example.

Little Big Assassins

I have based my level on the Assassin's Creed videogame. It is essentially a platforming stage however there are a few secrets to collect which will net you some extra rewards if you find them. The basis of the level has you assassinating a target given to you by the bureau. The end of the level has a massive fight with some guards.
I advise you to take a look at this level as well as those on the cool levels page in order to see some examples of positive level design and then try to come up with a theme before you start construction of your level.
