Fight Simulator [upd] - Omega Flowey

The mechanics are faithfully recreated: you have your classic red SOUL, the ability to switch between vertical and horizontal movement depending on the attack phase, and the desperate scramble to call upon the souls of your fallen friends to heal. The best simulators nail the speed and the density of the bullet patterns. When the screen is flooded with vines, lasers, and bombs, and the menacing 16-bit track is blaring, the game genuinely captures that heart-pounding, sweat-inducing panic that made the original fight so legendary.

: Competitive players have documented the RNG (Random Number Generation) patterns in the fight, identifying which attacks are procedurally generated and which are fixed script events. Omega Flowey Fight Simulator
