You're a drill digging endlessly downward. Steer LEFT and RIGHT to carve a tunnel through the soil. Your AIR drains constantly — grab the glowing amber pockets to breathe.
Jagged ROCK stops your descent cold; steer around it. And a rising FLOOD chases you from below the whole way down. Stall too long and it drowns you.
Hold ← / → (or A / D) to steer. The deeper you go, the faster it all gets.
