Thanks a lot for trying;
None of your tipps worked in the end; but thanks a lot, everyone, you inspired me to go on and not to give up!

1 - Hammer: well, it's only for repair, it seems
2 - Flintstone axe: was too short in my case
3 - Antler pickaxe: was beyond repair. I tried to build a work bench, but couldn't reach it
4 - fly: Might work, don't know how
5 - killing myself by conole or by fire probably impossible, as my bed is my problem

In the end, it was the spear! It reaches beyond other weapons.
Always wear a spear ^^

Wow, I was so upset. Let's put this under "weekend comedy"
Thanks everyone.
If this game wasn't a "work in progress" I would've been upset.
Still work to do, eh?
But good work so far.

Have fun everyone.
