The beginning room tells me the rules of the game, but not the objective, nor a lot of the mechanics. I don't really know what I have to achieve once I leave, why the radiation meter increases, how to manage hunger, where I'm going at all...
In future updates I'll definitely work in a way to explain the meters more in depth I can see how me barley explaining any of it can be a little irritating for some people. As for objective there really isn't one beside looking for other people. I do plan on adding more npcs and side quest stuff as well as elaborating more on certain in world things after the game jam finishes up. I appreciate the feed back helps to hear from a outside prospective.
