This absolutely wonderful adventure is sadly coming to a close and I am really wanting it to keep going

Well gang I have a actual problem. I normally play action games and immersive Sims and randomly picked up Dredge after hearing how good it is. I have absolutely loved it's nice peaceful vibe and super cool and unique lore and items. Sadly I have finished every quest except for the stone tablet quest which I will complete soon but am just so sad this game is over. It's just been so much fun. While I do want the game to keep going and while I have only caught about 90 of the unique species....it does not really appeal to keep fishing just for the purposes of collecting all the fish and so I think this game is pretty much done for me.

Does anyone have a suggestion for fun stuff to do in the game other than getting the rest of the species?

Does anyone have a recommendation for another game that is as chill, relaxing and interesting as this one?

Dredge is a really well done game and I am glad I gave it a try

Edit: the above comments include completion of the DLC.
