I can see that! During my second playthrough, I feel like I also fell in love with the sound design. The music and effects are just so well fitted.
Additionally, I wanted to ask, is it intentional that there's no chapter I? Because as far as I can see it goes straight from the prologue to chapter II.
And, just to be sure, in the full version, will it be possible to save your progress? My laptop gets tired really fast so even playing through the whole demo without any breaks was a challenge.
