The demo here seems to be working.
Good to hear. Sorry for the difficulty there, as the build here is the same as what's on Steam. It may be a Steam overlay issue. I tested the main game just now on Windows 10 downloaded from Steam and was able to use my mouse and keyboard inputs and play. I can also confirm the demo works on Deck with touch input. Try restarting Steam and see if that fixes the issue.
Appreciate you double-checking. The game seems fun by the way. I'll have to play a bit more of the demo, but enjoying it thus far.
What seems to happen here, is that the controller is not active in the main menu. If the mouse pointer isn't present I can't select an option there, so the menu appears to be 'dead'.
I'm wondering if it's something to do with having both mouse & controller active, or something with switching applications. To be fair, the mouse pointer on my 4K monitor can be a little difficult to see at times, but I've run into other games which tend to have the mouse disappear unless I tab to a different application and back. I tend to have multiple apps running, so it's conceivable something is amiss there.
Ahhh, this is very helpful for troubleshooting. Yes, as it currently is now, the main menu just uses the mouse. You can use a controller to drive the car and navigate dialogue, but at the moment the game is primarily mouse driven. We'll hopefully get a controller update out soon as we get everything working with Steam Deck.
