I played and enjoyed Chants of Sennaar and Jusant in the last few months. A recent standout game for me was Tunic. Check it out, it might suit you well as much as it did me. It has fighting but if you want you can enable easier combat or even “no fail mode” (invulnerability) from the menu. The game has a ton of hidden secrets and puzzles while being pretty and friendly to look at like the other two games. It is a great experience with or without the combat parts.

Which site? Choose another instance if yours is unreliable. That’s the advantage of a federated system. Or just have a second account at another instance.

It’s mostly for cycling, not too user friendly, not well documented, but very powerful once you figure out how to use it.
