This is well written for the genre. (A bit gory for my personal taste in stories, but that's neither here nor there). I do agree with Nils, if you were going to work on this some more, I think it might have more punch to it if it skips from the forest scene straight to where you're getting back into the car and talking to Johan and crew and realise what's going on.

Also, might be a good idea to give yourself a nickname instead of using your email so that the bots don't pick it up and start spamming you.

A tad dark for my taste.

You should check the "enable scrollbars" option, otherwise the select nickname page can block progression.

I think maybe it might have been more powerful if it had ended a tad sooner, just when we realize Johan is a ghost. As it was the last part was a bit like beating a dead horse, though I suppose that would be par for the course for the protagonist. ;)
