This was a pretty intriguing premise to work with. I think you did a good job trying to put everything together to give a kind of demo of what you'd want to do in a longer version. Since you're asking for feedback, I do think that some of the artwork didn't quite mesh well together (I think Nancy looked a bit out of place specifically) but at the same time I did like what you were doing with the angel and the different font. The music and sfx selection did work out well though and I think with more polish overall there's a lot you seem capable of doing in creating the right atmosphere! 

Hope you'll continue working on this, as there's a lot of promise with your hidden stat system and unreliable narrator! Best of luck!
