I appreciate the long post, thank you for playing!
It's a challenge to have the little guys be mysterious and intriguing, and also give the player enough information to be satisfied, and want to keep playing. I'll keep working on it. There is a way to get renewable clay(in a sense) and food, but no renewable wood currently, as I want to restrict the amount of un-diggable 'impassable' terrain that is created without the player's input.
I'm glad you like the sculptures, next update should have some changes to them you may enjoy.
'Combat' in suggestions was not necessarily something I *want* to add, just a suggestion which I'm considering. I also want the game to remain pretty chill, so any implementation of combat would probably more feel like 'conflict', or a tension between predators/prey, rather than a strategic problem for the player.
