I must say I didn't understand much of what to do. How to use the tools and the chest? I pressed E for interact on everything, but nothing ever happened. I could pick up wood and brought it to the tools, but couldn't figure out what to do with it. I was able to feed some seaweed to the mollusk and he seemed to eat it, but he didn't grow or anything, and he didn't eat any more.
The concept sounds very cool though, so I'm sure there some interesting content here that I missed!
