OMORI's Alternate Ending Mod
OMORI AMBIENs content starts late in the hikkomori route, a mysterious door opens in Sunnys house that permits him to talk to Mari in a new room not in the vanilla game. This acts as the central area you'll come back to as you find all the new keys throughout the existing Blackspace 1 and 2 stages, these existing areas are peppered with new things, and getting enough keys gets you to an entirely new place exclusive to this mod.
