Currently playing Slay the Spire and Moonlighter. I'm 77 hours into Slay the Spire and try to win with every character and unlock as many achievements as I can, but I just started Moonlighter today and I absolutely love it. It's feels like a nice Nintendo game (which it kinda is considering it'll get a Switch release). You run a shop. You get to price the items, you can upgrade your shop and the town. You have to enter a dungeon and fight to get items to sell. Of course you can also use the items to upgrade your sword and get armor, but no one expects the shopkeeper to explore the secret of the dungeon and become a hero himself...
I can almost defeat the first boss, but I'd be perfectly fine with just playing the game as a shopkeeping simulation. Sadly there's nothing really else to do inside the town (it only exists to explore the mysterious dungeons), but the game is really nice. During the day you sell your wares to the warriors and at night you fight your own way through them. I already love it and I only played 4 hours.
