Steam Deck testers have confirmed that the game works well when using the WASD controller layout.

However, the Steam Deck controls are not being detected correctly by default, and we’re currently investigating the cause.

Any additional feedback, testing, or technical help would be greatly appreciated while we wait for our own physical Steam Deck to arrive.

Edit: Some modifications have been made and according to those who tested it it already works by default with Steam Deck! I'll be reading the comments if there are any problems!
