Thank you for all your answers.

So it´s 5% skill loss per death. Gotta calculate which characters to grow, but I suppose they should be somehow specialized in certain weapons, not like my first allrounder.

What you explain not to do at night, is exactly what I did in a mindless meditative base building process, it just got a little dark too fast. I really didn´t expect the mob to be so angry and determined, just last day I became the animal whisperer who jumps through the fields like a bunny. Nothing can beat me in this game...I´m probably already overpowered. And then it hit me. Yes, That´s my lesson here.

I love the game mechanics and recognize how they´re intended. This is Rouguelike and I love it. It´s not even tagged as Roguelike.
