Reus 2 from Abbey Games recently had a big upgrade, and now it's Steam Deck Verified / SteamOS Compatible with full support from the developer.

What is it? It's all about shaping worlds as one of 6 powerful giants each with their own unique abilities. Your choices will determine the fate of the planet and its inhabitants. And as you progress, you'll unlock more new skills for your giants too. Humanity does its own thing though, and may even turn against you.
