Recreated an entire Undertale Battle (Mettaton EX) : r/scratch

Mettaton doesn’t want to kill you—he wants to entertain you. In a proper simulator, your "health" is secondary to your Viewer Rating. Each attack you dodge, each pose you strike (via the ACT menu), and each bomb you defuse raises or lowers your rating from "OK" to "STAR" to the coveted "LEGENDARY." Let your rating hit zero, and Mettaton cancels the show—game over. This shifts the player’s focus from survival to performance.

In the first half of the fight, survival is secondary to showmanship.
