Hello everyone, I just got the game and I'm very exited to discover the world and the story.
I wanted to ask you all for some tips and tricks, things you wish you knew at the beginning of the game. Also I do have some questions:
What should I do in the beginning? I did meet everyone, and my only mission is From Bud to Spud.
Should I grab anything I find on the ground (mushrooms, shells, etc.)? Or leave them for later?
Sorry if these are dumb questions. I appreciate any information given.
Thank you very much for your help
