Little Light Below / 光落深境 is an offline cave adventure by Kuan-Hao Chao. Guide Explorer, Mossling, Tock or Lumen through eight painted worlds with left, right and each traveler’s ability. All travelers, outfits, lantern colors and footstep styles are available from the start.
Start and controls
Choose Begin on the home screen for the expedition, or Continue to return to an interrupted run. Hold the left or right control to steer; use the ability button when its cooldown is ready. Settings also offers optional cave-half steering. Open the Wardrobe to choose a traveler, inspect its ability and preview walking or running.
Settings includes English or Traditional Chinese, reduced effects, sound and haptic controls. Decorative artwork and ordinary text do not respond to a long press. The explicit seed and challenge editors remain available for entering a course.
The Heart Lantern and resting lights
Restore the eight chapter beacons to open the Heartwell at floor 160. Its final ten floors have no chasing ceiling: land on each numbered light switch before passing its gate, then reach the Heart Lantern. Every traveler can finish without a required ability. A missed connection offers a retry instead of leaving you trapped.
Story difficulty saves resting lights seven and fourteen floors into each chapter, plus the finale’s circuit boundaries. A checkpoint retry restores health and keeps pending discoveries and total active time. It counts for story progress; uninterrupted times and no-damage awards remain separate. Adventure and Expert restart the whole stage. Ordinary background resume keeps your current run.
Optional three-light trails begin eight floors into each chapter. Repair their relays and bring a waiting traveler to the beacon to keep the rescue. Beacons add new features to the refuge. Relics do not gate the main ending; all 24 recovered memories unlock an extra constellation scene afterward. Camp offers story replays and links to the Journal and crew.
Landing Coach
After a failed run, a short tip may offer “Practice this footing.” This opens a ten-floor Mechanic Lab at 80% pace with the same traveler and world. “Retry original run” starts that course again from the beginning. Practice does not award competitive records or chapter progress.
Lantern Echo
Winning a new best time in Trial or Daily can record a small local route. Choose “Race your lantern” to show a lantern following that route on the matching course, with the same traveler. Older records without a recorded route remain valid. Your Echo does not collide, change scores, or alter the course, and its display is optional.
Progress, offline play and interruptions
Gameplay does not need an internet connection or account. Progress stays in this app’s storage on the device; there is no automatic transfer between Apple and Android phones. Switching apps or taking an interruption pauses the run. Resume it explicitly when you return. Avoid removing the app if you want to retain its local progress.
If artwork cannot load, use the displayed Retry action. If the game remains unresponsive, close and reopen it. Include the app version, device model, operating system, mode, traveler and course seed or Daily date when reporting a problem. A screenshot or short recording can help; do not send passwords or signing credentials.
