My comments on the game as a non-designer and a somewhat old-school gamer:
Game is rather short (won't take you more than 10 minutes on the 1st playthrough, even if you struggle to figure out where to go first). Afaik, this is the first draft of a larger project, so it is pretty straightforward for now - get to the place, do the job, the rest of apartment building has not much of interest.
I liked the multiple ending approach, depending on how thorough you search the apartments. Player controls are rather clunky, which makes it hard to combat threats. In my opinion this adds perfectly to the horror element =) but might be frustrating at times.
I like the visual look of the game - simplistic but neat. Color palette and lighting choices create a nice creepy atmosphere, along with eerie music.
Story is just enough for a short game. Eldritch abomination looks good, imo the best visual in the game, kinda wanted to see more of it being used in different scenes.
Overall a nice short horror (survival horror?) game. Will be checking for updates in the future, in case the game gets an expansion or smth.
