Oniria

Oniria is a single-level PWAD for Doom II, authored by Aluqah and designed for ZDoom. The new color scheme, that plays a significant role in the level, was created by Jon Dowland. At the 13th Annual Cacowards, the PWAD was listed as a runner-up alongside Zen Dynamics of Xaser.

In Oniria's story, you are having a nightmare from which you cannot awaken. You find yourself in a bizarre world where everything is black-and-white with the exception of the color red. The only thing you can do is to explore the world with the hope that the nightmare would eventually come to an end.

Walkthrough
While the visual look of the game has been altered substantially, the gameplay of the sole level does not differ much from a regular vanilla Doom level. A noteworthy feature, however, is the amount of keys. You actually have to find many items of the same type to unlock new areas. To make the progress easier, an info table of the found keys is visible on the screen by default. Obtaining the keys requires mainly slaughter of monsters. Their behavior has not been changed, and the black-and-white palette does not render them difficult to see, but there is a considerable amount of them (over 250 in the end). Aside from monsters, a few tricky parts are offered. Solving them requires jumping or accuracy to level detail.
