The game concept was really cool, even if I couldn't finish it. I think the game was way too dark and lighting up the game with the gun sounds interesting, but I personally didn't like it because the light duration is too short and too bright. I also couldn't find the last person (The child or father, idk who it was). I thought it would be the blue glass thing on the floor or maybe that was a red herring? I only got the bad ending since I gave up after a while.
Overall, interesting game that I think could be made better.
