In Infinity Dive, a free web game by keepeetron, you find yourself falling into a void containing a fractal curve. Using the pointer, you veer toward the curve as you fall toward it at ever greater speed. If ever you lose sight of the curve, you're dead. The curve comes at you faster and faster, but never gets closer.
a simple but gradually intense mouse-only game

A perfectly-simple concept, executed beautifully, with similarly minimal yet merciless audio that rewards you for progress with more tension.
