The basic premise is really cool and I like how it plays out at the end, but I think it may have been too ambitious with how much you actually include. It looks like a lot of effort was put into the assets and level design, it's a shame it doesn't always pay off.
I loved the voice acting in this, it really contributed to the overall creep factor. The survey at the start seems a little pointless; I kind of expected the things I tick to affect what I was going to be shown, but it looks like the drop down is the real key. That being said it's pretty cool that you have such a variety of scenarios, well done for finding the time to try and do it!
I think some of the scenarios could have probably been fleshed out a bit better, or just done with some better testing. For example I kept getting stuck on some of the geometry in the height fear, the doors in the darkness fear had to be opened multiple times to actually open, and I couldn't seem to escape some of the spiders in the spider fear. Overall I'd say the darkness fear was probably the most successful; you did a good job of building tension initially and I enjoyed the creepy setting and various items around the rooms, but the repetitive sounds and 'jump scares' lost it's effect pretty quickly. The other scenarios were a bit of a mixed bag, but some of the initial settings were pretty well done, they just didn't necessarily deliver.
It may have reduced dev time and created a more consistent experience if you'd stuck with one 'environment' but added in the scares that corresponded to the survey, e.g using the darkness scenario but adding in clowns or children or spiders or whatever else you saw fit. It also would have given you a chance to make more liberal use of the assets you had, as there were a fair few good ones that were pretty creepy/scary (especially the mannequins and clown creepers).
Overall I think it's a good effort and I'm really impressed with how many scenarios you created, but I think you may have been stretched a little too thin. Well done for your submission :)
