Same as others, when I clicked pop up that offered details, it said "download failed, please retry" lol. Seems lots of the Unity games have issues, but perhaps I have just run across several lately. Anyway, sounded interesting, hope you get it fixed.
I saw 3 different doors, could not seem to get through any but got a glitched view of the next room which had a couch in it. I never found any buttons to run into.
Nice game, good design and play. I would suggest a few more instructions on how to play for a more fluid player experience. Such as you need to click on John in order to move to the next screen, after objects and events are finished of course.
you can drop the skull using down key if you feel its too slow :)
