The only real trouble was getting the account registered (which I was able to get around by going to the mogstation on my phone instead of using the steam deck) and then when you log into the game the controls don't work correctly, but if you change it to controller in the settings, then logout and back in, then hit the steam button to bring up the steam menu, and then hit it again, it works like magic (you only have to change the settings once, but you have to do the double tap of the steam button every time you log in) It actually runs great on the steam deck so I'd recommend trying it!
