advice?

Honestly, there's no wrong way to play and there's tons of ways to get back on whatever track you were on, so i wouldn't stress too much! :) I would say, whenever you get an item, keep at least 2-3 in your inventory and when you find an artifact keep the first one you get before donating it to the museum. I would also keep track of the things you need for the community centre too. Good luck and I hope you're having fun! <3
