You’re in charge of hell and your job is to punish the filthy humans. They deserve it.
When a human reaches the end, they escape through a portal and get a swift death. Your job is to prevent that. But no matter what happens, once they all die they get to be punished again the next day.
Controls are mouse only. You can click on things, or drag the camera with the left mouse button. (WSAD and arrow keys also move the camera, but are not required.)
