For version 0.7.44:

The game seems to have a lot of potential, but I'm getting stuck pretty quickly just because I don't know how it's all meant to work. For instance, I had to figure out that E was the key to eat. And the interface in the top left with the three worms...

I have no clue what it is. I can see that Tab seems to cycle the jaw icon, but I have no idea what that implies. It doesn't seem to have any impact on my character.

I'm also not sure how the mating/egg mechanic works. And the fruits, what do those do? All of the tutorials and guides I can find are from over a year ago. Is there a more updated set of instructions somewhere?
