Although the visuals are pretty basic, I'm assuming you're a developer that's learning the craft, so all due respect. You should be proud of the sandbox you've created here - in some ways this made me think of the possibilities of where you could go next: The fact that the player could freely walk around and enter the house at the beginning without having to enter the store to get the plot moving made me think of things you could do for future projects that require the player to have the illusion of 'freewill.'
But this could also heighten tension and atmosphere, so something to think about for future.
The dev mechanics of the 'shopping' trope also feel like a device you've playing around with, so look forward to your future endeavours in this field.
Whoever the V/O actor is, I love it. I created my own narrative because of this, and although may have derailed from the ongoing arc, I had loads of fun commenting on the content. When the blood was originally seen I could tell where this was going, but at least I got to have some fun with it.
I want more Arnie.
