i’ll just add a few i haven’t seen yet:

• Chained Together - running gauntlets while … chained together
• Children of Morta - adorable graphics meet solid gameplay and vivid storytelling
• Core Keeper - top-down Terraria with great pixel art, full release in a week!
• Cosmoteer: Build your 2d-Spaceship and do what you want! Full workshop support with tons of available mods.
• (hmm so much stuff starting with c, gotta change my game)
• Element TD 2 - classic tower defense experience
• Heavenly Bodies - Adventure game with physics!
• Kingdom: Two Crowns - the right thing for chilling :-)
• Necesse: even more Terraria, but with a huge world and settlements to build and manage. Still in EA, and needs polish, but great game even now!
• Neon Chrome: Cyberpunk twin-stick shooter
• Operation Tango: Asymmetric Coop, one is a hacker, the other is the agent on the ground
• Streets of Rogue: “immersive sim”-top down twin stick action roguelite - i cant even describe it well, but it is heaps of fun and chaos can pop up around every corner!
• Synthetic: twin-stick shooter with tons of guns and a hefty difficulty later on
• Grim Dawn: ARPG, and one of the best in its class. Dated, but still updated (and gets a new expansion soon-ish!). community is running seasons which add new areas, items and whatnot! i’ve sunk 1500 hours into that one, so i am probably biased when i say give it a whirl.
