So the official campaign mode rules are that you keep all Abilities and one non-starting gear, non-party item Search card per mouse at the end of each Chapter.
They designed the game so that every chapter can be beaten by a group of zero-level mice (no extra gear, start with a single Ability). I found it was pretty easy with the Campaign mode rules, a user named thenightsshadow posted his house rules for a Difficult campaign.
