iFUi

iFUi is an indie first‑person puzzle‑adventure game released in 2023 by the independent studio Luminal Labs. Launched on iOS, Android, and Windows, the title is available through the App Store, Google Play, and Steam. Player characters navigate a surreal, modular environment where each room represents a different mathematical concept, and the core mechanic involves manipulating abstract geometries to open paths and reveal clues.

The gameplay of iFUi is built around a blend of spatial reasoning and narrative exploration. Players use a minimalist interface that highlights objects with subtle color cues, and actions are performed by tapping or using simple drag gestures. As the story progresses, the player learns to translate visual patterns into functional tools, such as rotating planes or projecting shadows, ultimately solving higher‑order puzzles that unlock the history behind the game's dreamlike landscapes.

Critics praised iFUi for its elegant design and engaging puzzles, though some noted that the narrative was unevenly paced. The game has been commended for its low-impact engine, offering fluid performance even on modest hardware, and for its soundtrack, which incorporates ambient tones that evolve alongside player progress.

Development of iFUi began in 2021, drawing inspiration from classic titles like Myst and The Witness, while integrating modern handheld controls. The studio employed a lean team of designers and programmers who iterated on puzzle mechanics through extensive playtesting.

Since its release, iFUi has maintained a dedicated following in the indie puzzle community and has been cited as an example of effective use of abstraction in mobile game design. Its success has encouraged Luminal Labs to pursue additional narrative‑driven puzzle projects.
