Very nice, short little game!
I really enjoyed playing it, although I wish it was a bit longer!
Loved the PS1 styled graphics too, really takes me back to the days.. The only point of criticism would be that it kind of throws you right into the action with the direct siren noise. I'd prefer if it would've build the tension a bit.
I hope you continue this project and expand it at one point, or maybe start a new one.
Also, I've made a video on my playthrough, hope you enjoy it as much as I did!
