Doomori

Doomori is a fan-made parody that slams together two genres that should never mix: the frantic first-person shooting of DOOM and the soft, surreal watercolour world of the RPG OMORI. You blast through four areas lifted straight from OMORI — Vast Forest, Otherworld, Black Space and Faraway — except now they are combat arenas packed with enemies to "rip, gun and tear" apart at high speed.

The result is deliberately absurd: cute, dreamlike scenery torn up by shotguns and rocket jumps, backed by an original soundtrack that leans into the joke. It is genuinely difficult, with tight arenas and aggressive enemy waves that punish standing still, so keep moving and use the terrain. Built by the team behind OMORI Multiplayer, it is a short, punchy novelty for anyone who has played either game. Fans of arena shooters like 1v1.LOL will click with the movement.
