The reason the menu is opened by pressing Q instead of X is because otherwise it would pop up all the time. You see, I didn't use any plugins for the menu, it was just common events and variables. Originally, it was opened with X, but while I was playtesting, I noticed that it opened randomly all the time, so I had no other choice but to assign it to Q. Next time, I'll just use a plugin to make things easier.
Regarding the footsteps sounds, I forgot to add the option to deactivate them.
Regarding the fall you mentioned: I actually I agree. That was bad design on my part and it would have made that scene better.
Finally, regarding Greta and her diaries. Yeah, bad design again. I didn't leave any hint so you have to figure it out by trying all the choices, which is not good at all. I need to avoid doing this in future projects lol. Trial and error is definitely not a fun experience.
Thank you so much for playing and for your feedback Beregon!
