Lol, I will keep this in mind!
Question, what do you use to play FPS if you do not have QWERTY keyboards?
Hello. Most of the time, I change the keys in the options and put "zqsd" instead of "wasd" or "up/down/left/right".
Or sometimes I use "up/down/left/right".
Finally, I found a solution for the games of the jam which did not allow keys remapping : go into the "system parameters" of the operating system, change layout to QWERTY. So when I pressed "z", it was like if I pressed "w", and pressing "q" was like pressing "a".
So it was not that much a problem after all. Keys remapping in the game options would be appreciated, but not indispensable.
I am quite satisfied to see people became aware of this issue, though.
