This is unfinished! I haven't documented anything yet, but perhaps figuring stuff out on your own is part of the fun!
Just a few hints to get you started:
0. Think about things logically.
1. Nothing is random. (aside from world generation)
2. Six is an important number.

Not really a game yet, but with potential
Very nice teaser promising interesting sandbox mechanics without a crafting grid.
I'm really curious how it'll turn out. Please continue working on it!
