Very good. The overall atmosphere was very oppressing and unsettling, with good audio design and no lazy jump scares. The retro-style graphics worked very well in further obscuring the already dark and unsettling environment, and also helped lessening the sparingly used gore.
For its runtime of 20 to 30 minutes, the game delivers a short but intriguing story. I like that the game has a defined conclusion and ending, but also leaves most of the overarching backstory shrouded in mystery.
