Apologies as well for the ramble :P I tried to be vague with the spoilers also.
Okay, if I had known what your story was about, I would've checked it sooner! The initial choice where you need to gather context is a pretty neat idea. I wanted to like the computer terminal UI, and while I understand it was due to lack of time, it quickly became annoying (especially on 2nd reading). Other than that, I think a simple loading screen when deploying/deleting would give the proper gravitas to your final decision.
The funny thing is: I actually guessed what the hidden option is without realizing what the clues were! (It couldn't be this, so what if I try this one? It was my first guess on the proper screen too—although I kinda fumbled a bit with the ask questions menu trying to figure it out.) So… that probably ruined the experience for me. I did look through the entries again because it felt like I cheated, but yeah looking back I did overthink the clues.
…Which unfortunately made the ending kinda fall flat for me. I mean, it was a hidden ending, so I guess I was expecting a twist that would reframe the whole choice, but it just made the choice easier. I also don't get why it needs to be hidden in the first place?
That said, I like the MC a lot (I also had a bit of experience with someone like them), but the sudden fast pace and focus on the virus near the end kinda took away from the story a little. I would've liked an additional entry that showed the MC's feelings and condition near the end—I was interested to know more about the MC's backstory, like their kids and earlier relationship with Fel.
I had a few more suggestions about the ending but it felt unwarranted so I took them out. Overall I liked it, but I guess I kinda ruined the experience for myself. Whoops. :3 Anyway, cheers!
