Hey - actually, we have already (in the patron version of the game) implemented a quick save option, so you can save at character gen, although that will also save your map seed, so you'll end up with the same map each time you load. We'll definitely add the ability to use the last character configuration, and eventually let you save character creation.
The tutorial is just a placeholder; the game is very unfinished, as we only started dev a few months ago. As we fill out the combat system, we'll start to introduce tutorials - right now we're trying to make sure things are explorable, for instance giving info on hover, although things like when it's possible to use contextual moves like "Sit on It" or "Grab It" are still opaque.
We've increased the amount of starting food, and there are a few other ways to get food, including spending time at the inn, which is somewhat "free" if you run out of gold in the latest patron build, defeating the Centaur in combat, or camping with the Orc after defeating her in combat.
Eventually you'll run out of food as is - since there's no end goal (or even the first in-game milestone goal!), we haven't added the ability to play infinitely. We might create that option in the patron version for messing around.
