I am wondering how much xp(days) you need to unlock various characters. I got Willow so far and I'm on 28th day. I want to try out a new character but do not quit the save I am playing now for it to turn out that I yet have got more xp(days) to go.

Also what can I do to not get bored in the game? I got all the things unlocked and built. I got more food than needed and the same enemies to kill... It just started to be repetitive - get resources to sustain living and kill all the mobs with ease.
