Just beautiful. The endings are pretty mysterious. I don't understand them, but I guess they fit since the whole game is abstract. Void at x994y1004 and x996y1004 is reachable.
Edit: @ Widget below: Oops, I meant x994y1004 and x994y1006. I have minor dyslexia.
Thanks everyone!
@sergiocornaga: Well, technically the flood at the archipelago is kind of a new area, different from the archipelago at the start ;) So I counted it as a second secret area, given that it is only accessible after visiting the demon dwellings.
@egomassive: Thank you for pointing those voids out. I'll check and fix them as soon as I can.
@dave.germain: I'm sorry the level confused you! This happened to one of my beta-testers and acting on his advice I added a couple of explanatory notes, but apparently they were not enough... eh. :/
