Have you played Alien on NES? I had Vietnamese flashbacks about exactly this after a couple of minutes.
Unusual, very atmospheric, with suspense. And it is difficult for people like me - those who do not know how to memorize sequences well at the level.
Perhaps more people will appreciate the game, if somehow simplify the process for them - show part of the level map open in previous attempts or mark previously checked sockets as "wrong". It can periodically give more light for a short time or allow you to escape from the enemy in certain ways.
