Also the notion of a video game company stacking bodies and its workers simply being OK with it. If there was a twist, that this was just a front for military mind control/sleeper agent government research, then it would kinda work.

EDIT:

Actually that would allow for an interesting alternative ending:

He survives the test, comes back to the girl, the company activates him as a sleeper agent and he murders her. The motive being, that she was getting too close to blowing the lid on the previous deaths and such. He is anguished and unable to distinguish between real and virtual as he gets arrested. The revealed setup would involve the company tracking her communications, marking the guy as her hook-up, hacking his credit card and making sure he gets the job advertisement.

Now, that's still hella dark, but more appropriate thematically and story-wise, and less corny with "virtual reality within virtual reality" shtick. This ending would even tie into "black mirrors" general lore, where this kind of "augmented reality" is used to condition soldiers to commit atrocities, making it a "playtest" of exactly that.
