Steam Deck compatibility has been confirmed by multiple users, and is now running the latest Linux build. In addition to this, cross-platform cloud saves are now in, so you can continue the journey between Mac, Linux and Windows. This means you can play on your PC, then take the journey with you on your Steam Deck!
The demo now also has a standalone store page here, where you can leave reviews on the demo specifically. If you want to support the demo, leaving a review will help with Steam's algorithm.
In addition, the Steam Demo has now been downloaded over 3,500 times! Thanks to everyone for their support! If you are enjoying the game, please remember to leave a review, as this helps the store algorithm. Happy puzzling! You can read the full press release here.
