Maybe is a bad question but i would know if there's any way to have a list of all quests of the game. I'm "stuck" with no quest and i don't know how to move on. I don't know who should i talk with or what i should do. Thanks for any help or support.

Yes, the walkthrough has all quests. ;)
You can check the quest log in the menu and toggle to the left or right to see "All" or "Finished" quests instead of just "Active" quests in case you want to see what you've already done.
Exploring is usually a good way to find something new to do. ;) Else there is a point at the main story after defeating Lace without a quest, at that point you have to return to Varea in Manastyr to get the next quest.
