A fellow Unreal Engine submission! Great job!
I concur with everyone else. I really enjoyed the way the narrative was presented and the visuals used; it was also a little difficult for me to figure out what to do next after the fire suppressant. I think that was a viewport shader used to give the 16-bit effect? Either way, looked really nice.
In terms of novel constructive feedback, I would probably say that I just wanted more things to do between bits of narrative. Without some combat, or more elaborate setups that needed to be solved, or even some cinematic stuff to mix it up, it started to very quickly feel like a walking sim to me, and I personally want more out of a dungeon crawler.
