The visuals were really nice, and the sound design was good. The main problem was that the "twist" moment was obvious from the first few seconds of the game. Removing the hud element in the lower left, as well as removing the signs explaining why there's a quarantine would have made a very big, positive difference.
The final moments of the game were very nicely timed and executed though, the timing was just right and I ended up with a smirk on my face.
Last but not least: I sadly have to admit that I at no moment felt scared or threatened, mostly because I realised that I was unable to run or move in any way that would facilitate fleeing or similar.
All in all, it holds together really, really well, but the few little tweaks I mentioned would've gone a long way I feel.
Thanks for making this!
