Really scary and really good jumpscares, i had goosebumps every single time that fucking thing showed up.
Also, great atmosphere, it was able to really encapsulate the feeling you get when you're a kid, and after going to the bathroom at night, you turn off the lights and go running to your bed.
2 things that could be better:
1 - If you don't turn off all of the lights, it just gives you a warning to turn them all off. It would be better if it just gave you a game over screen if you didn't turn them all off.
2 - Sometimes when all of the lights are turned off, except for one, and you're already in the bedroom, you can't see anything so you just have to restart the game. Try to make the lightswitches a little bit more apparent.
HM : If you changed the lightbulbs to lamps, it would be 100x scarier. But only a suggestion lol.
