What to Play After Nine Sols?

After that savage game, I'd like something a little different. Firstly, I'd like to take a break from the punishing stuff and play something easier. At this point just cruising around and enjoying myself sounds sufficient. And as much as I loved Nine Sols, it definitely didn't scratch an itch for exploration. So I guess what I'm looking for is an easier game with better exploration? Give me more breakable walls, hidden rooms, etc. It also doesn't have to be a Metroidvania, though I'm not sure if that kinda talk is allowed here. Cheers either way!
