Object Impermanence: Puzzle Game Where Looking Away Erases Reality
Slugware’s upcoming puzzle game Object Impermanence runs on a single unsettling rule: whatever leaves your field of view stops existing, moving or working the way it should. The Unity-built first-person title, currently slated for a Q4 2026 release, has just put that idea in front of the public via a free Steam demo that’s landed a “Very Positive” rating from early players.
Object Impermanence’s Core Mechanic: Vision Defines Reality
According to its official Steam listing, Object Impermanence is a first person puzzle game where your vision defines reality, and only the things you can see exist, tasking players to learn and master the strange behaviours of objects outside their vision as they traverse ancient structures. The store page spells out the practical effect on the world itself: doors open, elevators move, lights shine, fans blow, and critters scurry only when you see them.
Indie outlet 80.lv, which covered the game’s reveal, described the same trick from a design angle, noting the studio behind it “plays with the idea that objects stop moving or even existing when you don’t look at them.” The outlet also flagged one of the more inventive applications of the mechanic: the unusual mechanics allow for coping with in-game obstacles, such as crossing railways with a moving train, by controlling what does and doesn’t exist in the player’s sight line.
Steam Next Fest Preview Praises the “Aha” Moments
Niche Gamer got extended hands-on time with the demo during a recent Steam Next Fest and came away impressed by how the game escalates its central idea. The outlet explained that a big part of the puzzles revolves around small creatures that serve as living puzzle pieces, with some remaining active only when observed while others vanish the moment eye contact breaks, turning their behaviour into the foundation for many of the game’s challenges.
One example cited in the preview involves timing and spatial awareness in equal measure: a puzzle that requires positioning one creature on a pressure plate to lower a wall and reveal a second creature, then placing both on separate switches while maintaining visual contact, often solved by walking backwards to keep everything in frame. The reviewer summed up the overall pacing by noting the demo itself lasts around 30 minutes, which feels like the perfect length.
A Forgotten Planet and a Decaying Civilization
Beyond the mechanical hook, Object Impermanence wraps its puzzles in a science-fiction mystery. Per the official synopsis, a science expedition is sent to investigate a planet adrift in a vast void, where a ship malfunction leads to a rough landing, and with the vessel unable to carry the player home, the ruins ahead call to them, their doors opening only to those who see the patterns of the decayed reality.
The world’s underlying philosophy is baked into its lore rather than just its systems. The Steam page states plainly that for something to exist, it needs to be remembered, and everything that exists eventually degrades. Niche Gamer’s preview echoed the atmosphere this creates, describing a feeling of exploring the remains of a civilization abandoned long ago, where buildings crumble in the distance, strange formations float through the sky, and the setting has a dreamlike quality that makes it difficult to look away from.
Demo Reception and Wishlist Momentum Ahead of Q4 2026
The free Object Impermanence Demo went live on Steam on June 12, 2026, and has since collected a “Very Positive” rating, with the storefront showing 97% of its 155 user reviews in favour. That follows an earlier open playtest that Slugware ran through Steam, which the developer said drew nearly 1,900 participants and translated into a wishlist jump, with the studio thanking the community for helping the game reach “over 4000 new wishlists” off the back of that test alone.
The full game’s Steam page currently lists a Q4 2026 release window and marks the title as not yet available for purchase, with no user reviews yet logged for the main build. Slugware, credited on the game’s YouTube channel as founded by Julius Puke and Tom Jerbo with an original score by composer Jamal Green, has used the demo cycle to gather bug reports and balance feedback via Discord and a linked feedback form ahead of the eventual launch.
For puzzle fans in New Zealand and Australia hunting for something outside the usual roguelite and deckbuilder rotation, Object Impermanence’s Steam demo is free to download right now on Windows, giving regional players a low-risk way to test the perception-bending mechanic well before the Q4 2026 release window arrives.
