Controls work well I've tried on many PCs but there's no issue. WASD or try up down left right arrow keys for jump and move and for fire press space. Try arrow keys hope that will work.
Well, it's a new day, I've tried other games no problem, and gave your game a try again... and still, controls do not work for jumping for me, trying again french or english layout, still unable to play, I think there might be something because I don't have the problem with other games
Then there might be with your case but if possible then try on another pc. Im new to game development and its my first game and I've used unity's new input system. Don't know more what the problem is. I've tried on different PC's but I didn't faced this problem which you are facing.
