The storyline is a familiar one, of course. The narrator remains generic throughout, without a place on the lab team, and in fact so do the other characters. The explanations for each choice gives the narration a distinctly self-conscious air.
My overall impression was that it could use more polish. The writing feels rushed in places - as if it was trying to sketch out a scene and ran out of time. There are unfinished branches, which is a shame for a competition entry.
Without being emotionally invested in the narrator as a person, I felt no need to ensure their survival - instead finding all the branches felt like a story mapping exercise. There is definitely potential in the storyline to populate it with perhaps fewer but more realised characters to give the choices some emotional weight.
