Classic "the floor is lava" survival. A glowing red lava line starts near the bottom of the canvas and rises steadily over the round (faster in Hard mode). The detector tracks the lowest motion-active row in the camera view — i.e. the lowest visible part of the kid's body — and dings them a life every time that lowest point dips below the lava line. Three lives, score per second survived. A faint warning band right above the lava gives a visual cue to stay clear.
