Overall - interesting game, pixel graphics is fine for me, mood is very good (though I'm not a fan of horror games - that devil-like character scared me like Hell!)
Sometimes there are some voices heard - I would appreciate subtitles.
Esc is not closing manuals - was a surprise for me, getting used to use E.
No hint how to climb - figured it out.
Hint : 'Some containers can be opened and closed'. Is there such a container there, what is the key to do it?
Do you plan to introduce some bar showing life/sanity or is the blur effect the only one hinting it?
