Grandpa forgot his meds

Tomorrow morning, a commission is coming to inspect the renovation of an abandoned school. Tonight, you are the new night watchman. Also an electrician. Also an old man who really should have stayed home. Your shift starts with a few simple tasks: turn the lights back on, open the blocked-off sections, and make sure the place looks presentable before the inspectors arrive. Easy enough. Except the previous watchman disappeared, the staff definitely aren’t acting normal, and the school seems to be getting worse the more you fix it. The deeper you go, the less this feels like a normal job. What happened to the missing watchman? Why was the school really shut down? And most importantly: Did grandpa really forget to take his pills... or is everyone else finally seeing what’s been living in this school the whole time?
