From what I can tell, the reviewers here don't really understand what's going on with the Always Sometimes Monsters Demo. I'm not going to make a full review, because I'm not entirely sure that this is worthy of it anyway (no bonus for the devs here (it's an in-joke)), but I'll try my best to explain.
Basically, this is a free game where you play as a video game reporter going to the launch event of Always Sometimes Monsters, where a demo is available for everyone to try. After that, you have to return to your office and write a review for the game based on the demo.
If you're looking for a demo for Vagabond Dog's Always Sometimes Monsters, where you're supposed to look is inside the actual demo at the launch event in this game. It's an Inception thing; the demo for ASM is inside this game, and then you make a review afterward as part of an alternate experience that has little relation to ASM anyway.
Personally, I loved this. It was the most unique way I've experienced a demo for a game, and it definitely peaked my interest as to the style that Vagabond is going for with ASM. I'm definitely going to get the game now.
