Not sure if anyone has posted about this yet, but here's some information.
This is a supposed staircase simulator, with a twist. First off you may be thinking, wtf? But I Assure you this is worth a look. The goal is to reach the bottom of the staircase, that's it, but there will be things along the way that want to stop you. It's best played without knowing anything about it, but here's some information for you if you are interested in the back story of the experiment.
