The Omega Flowey Fight Simulator -2021 - (often referred to as the Photoshop Flowey Simulator) is a fan-made recreation of the climactic boss battle from the indie game Undertale. Created primarily for players who want to replay the boss fight without completing a full "Neutral Route" playthrough, these simulators are popular on platforms like Scratch, itch.io, and Minecraft . 🌻 Simulation Mechanics

The simulator aims for a "pixel-perfect" recreation of the original 2015 boss fight, including:

Attack Phases: Mimics the 10+ randomized attack patterns, including the flamethrowers, vines, bombs, and X-shaped pellets .

Soul Segments: Recreates the six mini-games where you call for help from the captured human souls (Cyan, Orange, Blue, Purple, Green, and Yellow) .

UI/Visuals: Includes the iconic "TV head" animations, "Your Best Nightmare" soundtrack, and the unsettling, realistic art style of the boss . 🎮 Version & Performance (2021-2024 Updates)

While the "2021" version was a milestone for browser-based play, newer simulators (V1.2+) have introduced several fixes:

Skip Intro: A button to bypass the initial dialogue for faster practice .

FPS Optimization: Fixed issues where vines spawned too fast on 60 FPS monitors (the original game runs at 30 FPS) .

Hitbox Adjustments: Improved collision detection for the "Giga Vine" and "Friendliness Pellets" .

TurboWarp Compatibility: Most modern Scratch versions are optimized for TurboWarp to reduce lag during "bullet hell" sequences . ⚠️ Known Bugs & Technical Issues

The "Invisible" Soul: On some versions, the health bar is drawn over the player sprite, making the SOUL invisible in the middle of the screen .

RNG Overlap: Because attacks are random, two difficult attacks (like the laser and flamethrower) can sometimes occur simultaneously, creating "unavoidable" damage scenarios .

Diagonal Movement: Many fan simulators use "non-normalized" diagonals, meaning you move faster when moving diagonally than when moving straight .
