Hahaha, yes, technically it's different forms. All of what I'm about to say is headcanon, because none of it made it into the game. But the idea was that you're the janitor at this company, working the night shift (wink), and when ''the Entity'' takes you. You become kind of like a monster janitor, absorbing the cursed essences of the major creatures you defeat.
And yyyeeeaah, I did end up removing one of the quarter level checkpoints, because I thought I had made it too easy. I just got too good at running through that level.
Also, thank you for playing and your feedback. Much appreciated.
