I get it completely, the last third of my submission is me running out of time and it's messy compared to the rest. I think you didn't need to go further with the gore, but have that last passage be a tiny bit less vague. It probably needed one or two more paragraph to get that scary/anxious feeling for the reader to give it a proper punch.
I will be following how this game pan out if you continue with it. I did enjoy it quite a lot!
