This is a puzzle-centered choice-based game about an operative at a water treatment plant who receives a haunting visit on Halloween.
Your goal is to take care of the plant and to deal with your unwanted (or wanted?) guest. At your disposal is the plant itself, which is modelled in surprising detail: multiple spaces to represent one room, multiple levels, machinery that can connect and disconnect, several short sub-games.
Story-wise, I found the overall concept of ‘the legend about an old employee’ neat and well-done. The antagonist felt a bit one-dimensional, so it could have been fun to find out more lore or learn more about them (although maybe I missed some areas).
This was a neat game overall.
