Gameplay - Mostly just a walking simulator except for the confrontations with Acmon which are very simplistic but functional. 3
Story - Interesting hook, but unfinished. 3
Presentation - The music was alright, the atmosphere sufficiently dark, and the voice acting was a nice touch. 4
Creativity - Quite a bit of optional worldbuilding through those two books at the back. 4
Horror - Mostly atmospheric but the unhinged voice acting rant at the end does help, and there's a lot of implied casual death and horror in the world itself. 3
Theme - The skull is there and does appear to have some curse to it but we don't really see it in action. 2
I enjoyed it overall, it's not my favorite but I'd definitely play it again if you add more to it later.
I did find a major bug though - after the flashback scene when it tells you to visit Franz, if you try to leave the map outside the MC's house through the south exit (heading towards the church), the game crashes with the following error:
Script 'crash's crashsteps' line 162: NoMethodError occured.
undefined method '[]' for nil:NilClass
