Pulse the screen edges like a heartbeat that speeds up as health drops

A low-health warning should feel like a pounding heart, with two quick beats and a pause, getting faster as things get worse. A simple fade in and out looks like a lamp, and changing its speed on the fly makes it hiccup. Here is how to do it without either flaw.

Why this works

Players feel a rhythm, not a brightness. A pulse with its two beats and a rest reads as a body in trouble, and because it is a position in a cycle that only moves forward, a change of pace never makes it jump.

When not to use it

Skip it for players who are sensitive to flashing or pulsing images, and in calm, slow games where constant pulsing would nag. Offer a switch to turn it off, or show low health with a steady colour or a quiet sound.
