The title made me try boarding up windows and doors straight away ^^ This is suuuper impressive for a first game, congrats \o/
I second the stuff already said in the comments. One more thing I noticed, when I was buying items, at one point I thought I wasn't getting anything from the chest but the blood was being used - I think it was just stacking items I already had. So its not actually a problem just a feedback thing :) love it!
