Evaluation

Oneiros launched on March 27, 2020 as a self-contained, narrative-driven puzzle adventure game. The store description presents it as a complete, finished experience — a single-player story about a character named Liam trying to escape a surreal version of his room. There is no mention of post-launch content, DLC, expansions, seasons, or ongoing development of any kind. The developer has posted no meaningful updates, patches, announcements, or developer communications in the game's news feed since launch. There are no DLC listings and no unreleased content on the store. The game appears to have shipped as a finished product and received no post-launch content cycle of any kind. With over six years having passed since release and no developer activity, the game is best understood as a completed, standalone title.

About this game

Liam wakes up late just like any other day, but something just feels different. Doors to his room are locked, laptop's hacked, phone's broken and something just doesn't feel right.
The place definitely looks like his room, but at the same time it just doesn't feel like it is, anymore.
He just had a weirdest dream ever, feels like his head is about to explode and he doesn't remember what he did yesterday.
Find out what's going on and help Liam escape.

Summary

Oneiros is a first-person, surreal puzzle adventure game that combines escape-room, classic adventure and crafting/building mechanics into a single narrative-based, surreal experience filled with psychedelic visions.
