Very much worth it, for the various games you get.
I played the story mode, which I found very enjoyable. It's funny how the cat is named Dodgeball. Kind of confused about the ending with the interrogation room/masked man. Here is how I liked the games:
Feed Me Billy - Probably my favorite, or second favorite. The music randomly becomes scary, despite the fact that you aren't being chased or anything, which I found unsettling. I should mention here (and this applies to other games, as well) that switching between objects is difficult and quite annoying. I'm aware you use the mouse wheel, but even when I'm not using the wheel, the objects will randomly change, and then I'll have to go back to the one I wanted. This happens again and again. Back to the game, though. I liked how the people try to run away after you shoot them. I'm curious to know more about the person who sent the killer notes through the mail, and who randomly appears at one point. And I want to learn more about the monster, too.
The Riverside Incident - I found this game to be deeply unsettling. For some reason the sensitivity was automatically very low and I couldn't figure out how to adjust it. Moreover, you can't sprint (at least not that I know of), so it was very slow. My screen was also unusually dark. For reference, I skimmed through a playthrough of this game after playing it, and their screen was normal. The grainy camera graphics combined with this strange darkness/inability to make out objects far away made for a terrifying experience. I think I kept getting teleported? I didn't know what was happening most of the time because the graphics and motion were so off. I ended up in a room with a doll and the screen started descending to darkness. The forest scene came next, but because there was no light whatsoever (come to think of it, there was a flashlight option or something, but the light would never turn on when I pressed the button?), it took a while to figure out where to go. The ending was abrupt. Overall this game didn't make much sense to me, and I felt a sense of fear I don't think I've felt during any other game. A visceral terror. Because the flashlight didn't work, and I couldn't predict anything.
Night Shift - Great game. I wish there were more convenience store games like this one. I don't really have any complaints. The death was very unexpected, because I was thinking I'd be killed in the bathroom and yet was killed elsewhere. Looking forward to playing Stay Out of the House (because the killer in this game is the same as the one in that game, I believe).
Spiders - Pretty forgettable due to the fact that the controls were weird and I couldn't figure out what exactly I should do. The issue of switching between objects was especially prominent here, with the game going from one object to another as I was being killed by spiders. I didn't spend much time on this game, however, so I'll come back to it in the future.
