Welcome, and thanks for submitting your game!
I'm usually not a super huge fan of first person but I thought the delivery method of the story fit it surprisingly well. I thought the twist landed quite well, and since the story is so short I found myself caught in the whirlwind of it rather than guessing what was going on. That's a plus to your writing, for sure.
A few accessibility suggestions:
- I found myself wanting to go back a page to re-read something, and since the game only allows going forward, I did miss a bit of the story. I'm one of those readers that likes to jump forwards and backwards a bit. I ended up having to restart the story to read it again, which wasn't my favourite. Perhaps adding a way to go forwards/backwards could help with this? Not everyone's a straight-forward, linear reader.
- Since it's a game, I felt the experience could benefit from a little audio stimulation, even if just a little bit. I created a horror text game (which you might find some inspiration) that was mostly a text-based story. But audio played a huge role in establishing the immersion and suspense aspects of the story. This will increase your 8KB size, but I'm wondering what role being 8KB is playing as a design pillar for you?
Overall, I thought this was a great story; you've clearly got a good handle on writing stories that make you want to keep reading until the end. A little sound and support for non-linear readers would take this to the next level!
