I played Daniel Linssen's Leap Year, and I highly recommend it! $5 for a delightful single sitting. Goofy mechanics whose depth you slowly discover by exploring and experimenting. Some of the most brilliant level design I've seen.

Mighty Switch Force is apparently really fun. The music is like candy. Same composer as Shovel Knight -- Jake Kaufman.

BOTW was my first Zelda game. Absolutely zero background needed. If I hadn't heard of the other games, I would have thought it was the first one in the series.

Wonderful, complex, textured music. Fades in and out of the ambience as if just another sound of nature.

It sounds like you might really like auto-battlers, also called "auto-chess" style games. Auto Chess started as a Dota 2 mod, and now Dota has their own called Underlords. League of Legends also has an auto-battler spinoff; it's called Teamfight Tactics. And don't sleep on the indie Super Auto Pets. It's pure fun.
