Object Impermanence: Puzzle Game Where Looking Away Erases Reality

A new puzzle game is asking players to confront a very literal fear of things vanishing the second they stop paying attention. Object Impermanence, revealed via a new trailer and covered by Rock Paper Shotgun, is built entirely around the idea that objects, obstacles and even hazards cease to exist the instant they leave your field of view. Developed by Slugware, the game is aiming for a Q4 2026 release, with a demo already playable on Steam.

Object Impermanence’s Core Mechanic Ties Vision to Existence

The concept draws its name from developmental psychology, referencing the phenomenon where infants genuinely believe an object stops existing once it’s out of sight, a milestone known as object permanence. According to Rock Paper Shotgun’s Oisin Kuhnke, Slugware has flipped that childhood confusion into a deliberate game rule: nothing in the world persists unless the player is actively looking at it.

That single conceit reportedly ripples through every puzzle in the demo. Kuhnke describes a sequence where a ball must be rolled through a pipe, but it only keeps moving while the player keeps glancing at it through gaps along the way, forcing constant repositioning of the camera just to maintain momentum. It’s a mechanic that turns basic spatial awareness into the actual challenge, rather than a side effect of exploration.

Alien Ruins Setting Follows a Crash-Landed Science Team

Object Impermanence isn’t just a mechanical exercise, it’s wrapped in a science-fiction framing. Per Rock Paper Shotgun’s description of the reveal trailer, players take on the role of a member of a science expedition sent to investigate a distant planet, only for their ship to crash land among the ruins of a long-dead alien civilisation.

That backdrop gives the disappearing-object rule a narrative logic beyond pure puzzle mechanics, hinting that whatever wiped out the planet’s original inhabitants might be tied to the same strange physics governing what does and doesn’t exist when unobserved. It also positions the game alongside a wave of recent narrative-driven puzzlers that use environmental storytelling through ruins and artefacts rather than dialogue-heavy exposition.

Puzzle Design Echoes Portal’s Object-Based Logic

Kuhnke’s report draws a direct comparison to Valve’s Portal series, noting that Object Impermanence leans on similarly physical, object-carrying puzzle logic, where alien spheres need to be manoeuvred into specific slots to trigger doors and mechanisms. The twist is that the usual rules of physics and continuity don’t apply if you’re not watching closely enough.

The trailer reportedly shows this pushed into more inventive territory too. One example cited by Rock Paper Shotgun involves a sewer grate blocking a passage, which can only be bypassed by turning around so it’s no longer visible, then walking backwards through the space it previously occupied. Another moment shows a train car bearing down on the player character, only for it to disappear the instant they avert their gaze, avoiding what should have been a fatal collision.

That kind of tension, using a purely optional camera movement as a life-or-death dodge, suggests Slugware is trying to build genuine stakes into a concept that could easily have stayed a one-note gimmick. Kuhnke’s write-up frames the reveal as promising precisely because of how many different systems the studio has already found to bend around the same central rule.

Steam Demo Live Now Ahead of Q4 2026 Launch

Object Impermanence is currently listed on Steam with a wishlist page and a downloadable demo, giving curious players a chance to test the mechanic firsthand before the full release. Slugware has not attached a firm date beyond the Q4 2026 window, which leaves room for the game to land anywhere from October through December.

For gamers in New Zealand and Australia, Steam listings and demos are typically available for download at launch regardless of region, so there’s no need to wait on a separate local release window to try it out. Given the growing appetite among PC puzzle fans for mechanically inventive, single-idea games in the vein of Superliminal or The Witness’s environmental logic, Object Impermanence looks positioned to find an audience well before its Q4 2026 target if the final build lives up to the reveal trailer’s tricks.
