I figured the hotkey things, i was in azerty so i had to rename the keys in settings. But for the windows thing its a bit annoying, i had checked the setting and didnt find the fullscreen setting but i'll look tomorrow/ Just finished the tutorial, the signal thing is really hard to understand but now that I know that theres no rush i can play and keep being dumb while not being stressed by time. Thanks for your help, I hope it'll be easier as I play!
