Endless Well Dive With Gun Boots

An endless dive down a bottomless well, built by one prompt into one HTML file. Your boots fire straight down: every shot brakes your fall and breaks what is under you, and stomping an enemy refills the boots and chains a combo that pays out in gems. Hand-drawn chunks get harder every 100 m, a shop every 400 m sells upgrades like triple shot and quake stomp, and a daily dive gives everyone the same well. One line reskins it.
