I need to check out that highscore thing, that could be really useful.

Anyways, you could put in a puzzle (I'm a huge fan of puzzles).

At first it seems to hard to do those, but it's pretty easy once you got an idea.

It can be as simple as having to find a way around something, which, for example hurts.

Just try to be creative and it works, trust me.

Items?

Carrots, food (for sugar rush) and maybe a very well hidden one up.

Maybe also a shield?
