Yes, keyboard works fine. I'd guess you need to unplug your controller because it seems like it's getting detected and taking priority.

Edit: Default Mouse + Keyboard Keybind:

Thanks for your answer, but after checking the troubleshooting section of the forum, it appears that many people have the same problem : only the key "s" does anything, so we can't play the game. I guess that I can only refound.

That's a really weird bug. I don't suppose you have a USB keyboard you could try ? (Assuming you're on a laptop)

i may be late but you can also use your mouse to do everything

Was there any fix to this? The game works fine on my Steam Deck but not on my Desktop PC. I can only go up and down with W and S, not hit select

Edit: Per the troubleshooting section of this forum, I found out that La Pucelle really doesn't like foot pedals. Removing the pedal fixed my inputs.
