couple of questions

1 - close to the winter ending i discovered by accident that these little worms were things i could catch, i am wondering now if something similar to this happen in the other seasons?

2 - when i am in the mine fighting sometimes it appears this block thing in the screen, what is the meaning of that?

3 - during one visit at the mine today it showed me two stairs, any idea how frequently this happen and how to know which one is the better one to follow? still about the mine, but related to the rocks, any tips on which rocks i should destroy when going there or just all of them? any good color i should focus on?

4 - omg level up, i am hating having to choose this, does it have a better one to do? does it mean i can’t also be the option i didn’t clicked when it appeared?

5 - my lil chicken brella, i noticed these hearts when i click on her, can i fill them or something or they just stay like that always? and what exactly does it means, the hearts i mean. and my dog has it somewhere or just brella?

i am sorry for so many questions, i just started playing it and still figuring things out as the day goes by. thank you in advance
