The starting tile doesn't count as Lily has to enter the tile for it to be newly explored.And believe me, her ability isn't overpowered - it's perfect. You use the cheese for a lot of stuff during the course of a chapter, even giving some from one character to another.
Lily, Collin, and Maginos tend to build cheese faster than the others because their cheese gaining abilities are easier to pull off, but what ends up happening is either they use the cheese for other abilities so that the mice survive, or they share the cheese so the party is better prepared for whatever they face.
Nez is an absolute powerhouse when used the right way, but he's terrible at gaining cheese, so he almost always needs help in that area, but his abilities that the cheese can power are so cool that you'll have no worry at all about giving up one mouse's cheese to power him.
