I'm sure some of these ideas have been talked to death but I figured I would just throw these out there and hope that something sticks
I really love valheim so here are some things I thought would make the game more fun.
Use resin for staining/protecting wood
Make a diablo style inventory screen for armor and weapons
Make a light armor equivalent for each animal in each biome. The skull/trophy is the helmet (deer,boar,wolf,leech)
Each one having its own bonuses. (deer makes you run faster wolf increases attack speed etc)
Make a sharper angled and flat roof
Make all food sources a farmable item (berries flowers)
Make paint patterns as a decoration for houses
Make a throwing axe that comes back when your throw it
Ridable bird mugin
Better stone textures
Make building a skill
As it levels up your constructions have a cleaner and sharper texture to them
Straighten the wood
Make sailing a skill (faster rowing, faster turning, wind favor ability)
There is obviously so much more that I missed but this game has so much potential. I just want to put it out there because who knows right.
Let me know if you think I missed anything that would be cool.
