good concept, but execution can be better! I don't think spamming a key a random amount of times as a response to an event (aka QTE) is a good idea. I'd want to listen/look for signs then turn the lights on immediately to look for the killer; right now I'm kinda stuck between wanting to wait longer to determine the source of the sound, or face away from the source and spam at the sun so it turns on before everyone's dead.
This is in addition to other comments tho. With more polish, tThis could be made into a nice game.
