Hotfix 1.1.2 is live! It aims to fix the issues Steam Deck users were encountering when trying to launch the game. We knew how important it was for Deck players and we appreciate the patience you've shown while we worked on a solution.
While this is not full Steam Deck support yet, we're currently looking into making The Angler fully compatible with Valve's handheld in the future.
In the meantime, happy angling - from wherever you want!
