When you first play this game, it’ll seem bloody ridiculous to beat or even get a decent score on, partially because the instructions in-game, in my opinion, are absolute bullocks. However, once you’ve got the hang of things, it’s really not all that difficult.
To start with, get to know the elements of the game:
Moody is the one controlling “the eye”, and the spider things that come from the floor, is up against the north wall. He moves against the wall only, in a left-right motion. If you touch him, your game is over.
The Eye is an extension of Moody used to detect you. It’ll move in: zig-zag motions either up and down or side to side, sweeping across the room in an attempt to find you; in a free-form motion following you, or it’ll disappear and pop back up where you were last standing.
