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.

Additionally, the game will be participating in the upcoming Steam Next Fest starting from June 15, alongside with the release of a major content update and brand-new trailer.
