The puzzles are decent, but the enemy takes away from the atmosphere and any tension that could have happened, and only adds frustration having to go out of your way to avoid him while he loops the exact same pattern the entire game. Can also hear you walking when on a floor above or below you, forcing you to crouch often which has you move extremely slow.

Would have been much better without the enemy, and working more on general atmosphere and sound, and focusing on refining and adding additional puzzles.
