Yeah. I would probably start with Dave the Diver, in their case.

It’s so good. Decently chill. Great vibe throughout. The Boss fights each have a simple gimmick to win, and they don’t try to be clever about it. (Nothing pisses me off like “we changed the pattern of interaction five to turn a narrow victory win into a loss”. Game designers need to cut that out.) Thankfully Dave the Diver has the classic two patterns per battle, and aims for predictable fun. And the Boss fights are rare, anyway.
