A neat little game with a nice hide and seek style horror element thrown in, the premise is nice and it does capture the essence of what a night shift would feel like in a cinema.
In the next upcoming nights maybe there could be something else other than the shadow, something that you have to flash your torch at to make it go away (if both spawned together it would be an unlucky death) , maybe there could be a few more spooks coming from the cinema speakers perhaps maybe throwing a few fake sounds to make you less prepared for the shawdow when it appears, maybe there could also be a few horror images thrown up on the screen so the player could look at it and get caught unaware or writing on the walls to distract the player.
The game over all is a pleasant experience and fun to play, it feels very slenderman like , it will be interesting to see what else gets included in future nights.
