Yes, we plan to add Steam Deck support for the game!
We are looking for ways to implement the native Steam Deck support for Shop Crush. We believe the game would work great on a portable device, so we hope it will be possible.
We won't be bringing the game to Steam Deck for the Demo, but we will try to add a Game Pad support, which will be a decent first step in that direction.
Thank you for your attention.
