Invest in Your Skills to Survive in Craftopia

The skill menu in Craftopia.
It's a shame the 'more inventory' skill isn't implemented yet, but that's Early Access for you.

Gaining experience to unlock new skills is another major part of increasing your character's strength. These skills can help make gathering and crafting easier, improve your combat capabilities, or give you new skills to use in and out of battle. Keep in mind that as an Early Access game, Craftopia doesn't have every skill implemented yet, and the skill descriptions give little explanation as to how skills improve from one level to the next.
