What's the benefit of levelling up?
I've seen a lot of posts showing how to level up quickly and complaining about XP caps (a cap on donations? that's my grrrr!)
But really why level up? You get a currant boost for each of the lower levels, and a bigger energy pot, which means a big new day energy boost, but I always use more than one potful of energy in a day anyway, so the energy I get from eating is more important to me than the new day boost. Also as your energy pot gets bigger the energy cost of teleporting leaps up.
