Save 75% on Gone Home on Steam A walking sim with a good atmosphere and an interesting story. It actually kind of spooked me at first but there are no jumpscares or anything like that.
Save 46% on The Oh...Sir! Saga on Steam I've actually only played the insult simulator and not the hollywood roast but the bundle price is well worth just the first game.
From the steam page: "Never Alone is an atmospheric puzzle platformer developed in collaboration with the Iñupiat, an Alaska Native people, drawn from a traditional story that has been shared across the generations."
Save 67% on Pony Island on Steam A puzzle game with some side scrolling elements. What if the Devil tried to steal your soul through a video game about ponies?
Save 75% on Braid on Steam Braid is actually an older game but I think it still stands the test of time-- ironically, because time is a major component of the game. Really interesting mechanics for a puzzle platformer.
Save 80% on NightSky on Steam A casual physics-based puzzle platformer. It doesn't offer much as far as story goes, but I find the sounds and gameplay to be really soothing when I'm stressed.
Save 80% on Crypt of the NecroDancer on Steam The love child of rhythm games and roguelite games. I'm not a roguelite fan, but I love this game! It doesn't feel defeatist at all and has a great soundtrack.
Save 33% on Planet Coaster on Steam Probably the most expensive rec on here, but worth it. It's basically what Rollercoaster Tycoon 3 tried and failed to be.
Save 90% on Retro Game Crunch on Steam So I'll be honest. I would only rec this at full price if you like to support indie game devs and game jam style games in general. But on sale, it's well worth it just for End of Line alone!
And you don't need Steam Controller for it if you already have one! It supports: Xbox One or 360 Wired Controller, Xbox 360 Wireless Controller for Windows, Logitech Wireless Gamepad F710, or keyboard and mouse
