Description (written by the developer; not a statement by this register)

Hiding in your own basement - your objective is to watch and report any anomalies you see through your house's CCTV cameras, and to survive until it's morning. Too many anomalies - and you're done for. Are you ready to take on the challenge and see if you can find all the anomalies before it's too late?
