A downloadable game for Windows

Oneiro is a "permanent prototype" 1st person 3D action-adventure game in which the player travels through a surreal and sometimes disquieting dream world. The player's goal is to escape back into reality - exploring, solving puzzles, and sometimes fighting their way through the dream in the process. Each level corresponds to a different section of the dreamscape, which varies greatly in terms of content.

Gave it a go....


Thanks for the vid, I appreciate it! You were on the right track but to get past David you will have to hit him in the head until he dies. That means finding a taller place to jump and attack from because his head is up so high.

There's also a video walkthrough on the main Oneiro website if you get really stuck.
