Y'know, what really sucks is that the idea behind trying to find your lost kid in an abandoned kindergarten, flooded by monster versions of its mascots, isn't even a bad one. I'm not saying I could do better, but I at least came up with something that... might be a bit original, kinda? You're familiar with the Corruptus Effect from that Abandoned by Disney creepypasta trilogy? It's something similar to that, very broadly speaking. But nah, let's make a secret science facility under a kindergarten where they experiment with new ways to create life in order to make daycare attendants, because that makes sense and isn't a tired trope.
Remember that one of the brothers made a disgusting simulator where you LITERALLY play as a kid trying to stop a school shooter but you can never stop him. He always goes through with it.
