"Before we start, you are…
…a potato."
Finally, a game I truly put myself into. How original for me to say 
I hope I don't sound rude-
Okay! So, I like this! If I can say this, I think the title should just be The Fifth Horseman as it, personally, sounds a little more ominous, especially for Fear? Totally up to you of course. It still caught my attention, and that’s really what matters in the end. I’m gonna sound like a pretentious asshole when I write this, considering I’m not even a professional writer; there are parts to the writing that could flow better. If that makes sense. I struggle so much with this too, so it really helps to have a second set of eyes to read this such as a friend or parent. My mother, an avid reader, has read my work a few times and can help me look at things a little differently to find what needs to be changed. Highly recommend reading it out loud. Like picking names, if it doesn’t roll off the tongue or if it sounds “off”, it might need some adjustments.
There are some little errors, like missed punctuation and missing line spaces between different characters speaking, but it didn’t take me out of the story. The pacing, personally, feels a bit rushed, but I know that this is focusing on MC living as a supposed human remaining their memories. It’s just something I’d thought I’d mention. (Do I sound like an asshole now-?
) When meeting “Dr. Greymark”, it would be nice to include options of shaking her hand, or hesitating to shake it, or outright denying it. Not necessary, and up to you, but it could be a small way of building MC’s personality or just having more control of MC’s responses. Also, was your comment supposed to stay in? I loved it all the same, it was so surprising!
I didn’t run into any coding errors on my run, even when choosing to input my own name, so from the first playthrough, everything is good! I’m eyeballing Famine tho. I’m comin for you b o i.
Quick edit: if you need help editing, I’d be willing to lend a hand! I’m not a pro, by any means, but if I can offer any assistance, I’d like to.
