About:
A one-button cave flyer in the spirit of the 2000s Flash classics, built from scratch for Leetdom. You are a lantern-moth with a glowing tail: press and hold anywhere to climb, let go to drop, and thread an endless cave whose ceiling and floor wobble, narrow and lurch while rock slabs hang in the way. How far you get is your score.
Every 450 metres the cave changes: Amber Hollow, Mossglow Deep, Crystal Veins, Ember Depths and The Hush, each with its own light and its own key for the soft generated music. It speeds up and tightens slowly, so a good run gets harder the longer it lasts. Your previous best is marked in the cave as a dashed line, so you can see it coming and fly past it. Glowing motes along the way buy new wings, seven in all, from the free Ember Moth up to a colour-shifting Prism.
Everything you see and hear is drawn and synthesised in code. There are no downloaded images, fonts or sounds. It plays best with the phone held sideways.

Phone check: 2026-09-29: Leetdom in-house build. Played on a simulated landscape phone (844x390, real CDP touch): holding a touch raised the moth and releasing let it fall; crash, game over and one-tap restart all worked; the pause button, the tap to resume and buying and equipping wings by touch all worked. An autopilot run reached 1,634 m (fourth cave). Portrait shows the game letterboxed with a turn-sideways hint. No console errors and no network requests beyond the game's own two files.
