I can't read their minds but it seems the devs don't expect anyone to reach 100 in any skills, the death penalty shows this, this games about creativity, planning, execution, journeying and having some nice food.

I'm near 500 days in a character and highest skill is running at 79 and I don't ever see me getting to 100 cause I'm gonna die someday soon doing something and that's going to send me back. When the games finished I plan on beating it before it hits 365 days cause Odin needs to be impressed with my skill not my skill level.
