I can't play the game at fullscreen and I also cannot see everything.
I actually found a workaround and it was lowering the scale of my desktop to 200%.
I then realized that there IS an option to toggle the fullscreen mode, but I couldn't even see it until I did what I mentioned earlier.
I think that this is an issue worth mentioning because the first impression is very important, and that could end up giving a negative experience for some people.
That being said, I absolutely love this short prologue and it's 5 stars for me!
I'm now going to start playing the full game...
