Object Impermanence is a puzzle game where things vanish the moment you stop looking at them

Object Impermanence is an upcoming first-person puzzle game from Slugware built around one core mechanic: if you look away from something, it ceases to exist. The reveal trailer dropped on July 4, 2026.

The setup draws clear inspiration from Portal-style puzzle design — you pick up and place objects to trigger doors and solve environmental puzzles. The twist is that most objects only persist while you're actively looking at them, so managing your gaze becomes the central challenge. The game is set on an alien planet where your science expedition has crash-landed, and you're left exploring the ruins of a long-dead civilization to piece together what happened. Those alien-looking balls you carry and place around the environment are the main puzzle tool, and the whole thing leans into the philosophical concept of object permanence — the developmental milestone where humans (and babies very much still learning it) understand that things continue to exist even when out of sight.

Object Impermanence flips that idea on its head as a gameplay mechanic, which is a genuinely clever hook for a puzzle game. Slugware appears to be a small or indie studio, and this looks to be a debut or early release for them based on available information.

No release date or platform details were confirmed alongside the reveal trailer.
