Gameplay:

I spent:
- 300h chopping wood,
- 80h building storage for more wood
- 3h grinding ressources to upgrade my axe to chop wood more efficiently

Enemy design:
- There are small trees which can be defeated in a bare knuckle fight.
- Regular Trees which require at least a stone axe to be killed,
- Boss trees can be taken down if you come prepared (by bringing a better axe)

Conclusion: Need more Wood
