Hey, that's neat:) I'd suggest that, maybe, you should change the footsteps sound, add some ambient noises (wind and distant city sounds, when entering the tower and various creepy sounds in the tower itself like metal creaking and something crawling up and down the walls, for example) and add something chasing the player down those platforms, when the light is turned off. Other than that, It's a cool little game, I enjoyed it:)
