About this game
Temlegen takes place after a reboot of the universe. Because of these events, you find yourself trapped in a parallel reality, where every step brings you closer to a difficult and irreversible choice. You play as Tan Kyuu, awakening inside a futuristic underground complex filled with labyrinths, traps, and unfamiliar faces. Strangers surround you — people pulled into this place by forces beyond their understanding. There is a way forward, but no clear way back.
Explore
Discover the underground complex: corridors, rooms, and hidden paths reveal pieces of the story. You’ll uncover secrets and consequences — not all of them welcome.
Make choices
Every decision counts. Some choices move the story forward, others lead to different endings. Your actions shape the story, and seeing everything in a single playthrough is almost impossible.
Experience horror elements
Temlegen includes tense horror elements that can startle you. You’ll need quick reflexes and sharp reactions to face what happens. Temlegen is a big experiment that contains a story waiting to be discovered.
