tfishell: You're looking for a site that has save game files, or maybe there's a subreddit for that or ask on "Tunic" Steam discussions forum.
I've already searched online for game saves for Tunic, but couldn't find anything. So I thought that maybe one of the players here in the forum might have a save file lying around somewhere. That's the only reason I posted my question here. As a last resort, so to speak. :-)
ConsulCaesar: This is a reasonable question to ask in these forums. I have shared save files here for other games in the past to help people in different situations. Unfortunately I don't own Tunic so I can't help with this one.
Another place to look could be the GOG Tunic subforum:
https://www.gog.com/forum/tunic#1740691656 Again unfortunately, like most game specific subforums on GOG, it's not very active.
Thank you for your help. :-) I also think that such a question can certainly be asked in a forum with a lot of PC gamers. And I explained above why I did it here. Thank you also for that link. :-)
