Hmmm, did you try pressing "Z" on that screen. I regretted deeply not adding an explicit instruction about this.As for fullscreen, I tried, but the input focus gets messed up.
Now it works well. At first Z/Enter did not work. Maybe it came from my side, sorry. Thanks for your reply.
Thank you for not giving up! :)
I don't get any sound, is it normal ?
