New Portal-like 3D puzzle-platformer centered on light and shadow – 'THANKS, LIGHT.' on PlayStation®5 and Steam This September! 

[10th Mar 2026, Hong Kong] Game Source Entertainment (GSE) is pleased to announce that THANKS, LIGHT., a 3D portal-like puzzle-platformer developed by South Korean indie studio Lightersgames, is scheduled for official release on PlayStation®5 and Steam in September 2026. The free demo version is now available on Steam, offering a first look at the mechanic in action, with wishlisting now open ahead of this year's launch. The game's central concept is a spatial manipulation of shadow and substance: players wield a flashlight to shift objects between 2D and 3D states, start your adventure by solving puzzles with your imaginations in the Liminal Space. 

Every shape has a truth behind its face——

THANKS, LIGHT. marks the debut release from South Korean indie studio Lightersgames. Positioned squarely alongside first-person puzzle-platformers like Portal, Superliminal, Viewfinder, and The Talos Principle, the game introduces a deceptively simple mechanical premise: Under illumination, a silhouette transforms into a tangible 3D object. When the light is absorbed, 3D objects are folded seamlessly back into a flat, two-dimensional form. There are no lengthy tutorials here. Instead, you must rely on observation and reasoning, approaching problems from different angles and experimenting with various possibilities to discover. Immerse yourselves into the puzzle-solving experience and master your own game rules in the world of THANKS, LIGHT.. 

The game has received honours twice at Korea's indie game event, INDIECRAFT. It also earned a spot in the prestigious "Selected Indie 80" showcase at Tokyo Game Show 2025.

A free demo is now available on Steam, offering you a first glimpse into a world built for perfection. Here, light, shadow, dimension, and perception intertwine, hinting at deeper truths waiting to be uncovered.
