Omega Flowey Simulator is a fan-made game based on the Omega Flowey battle from Undertale. Instead of limiting the player to Frisk’s side of the encounter, some versions allow control of Omega Flowey and provide access to his attacks. The game does not introduce a separate campaign or a new storyline. Its setting recreates the final confrontation in the Neutral Route, where Flowey uses the six human souls to transform into a larger form and control the battle.

Control the Boss Battle

Gameplay takes place in a combat arena where the player attacks a heart-shaped soul representing Frisk. When controlling Omega Flowey, players can launch projectiles, place bombs, summon vines, and use other attacks inspired by the original encounter. The objective is to reduce the opponent’s health while controlling the timing and direction of each attack. Some editions also include a Frisk mode, allowing players to dodge incoming patterns and experience the fight from the opposite perspective.

Attacks and Available Modes

Omega Flowey Simulator does not use traditional numbered levels. Its structure is based on battle modes, attack testing, and repeated attempts against the same boss encounter. Depending on the version, players may be able to:

•         Control Omega Flowey or Frisk
•         Fire pellets toward the opponent
•         Launch bombs and wider projectile patterns
•         Summon vines at selected positions
•         Dodge attacks with the soul
•         Practise individual attack sequences
•         Replay the fight to improve the result

Controls vary between releases. One Game Jolt version uses W for pellets, B for bombs, and Z for attacks, while another browser edition assigns several attacks to Z, X, V, and B.

Learning the Attack Patterns

When playing as Frisk, movement and timing are the main priorities. The player must watch where projectiles appear, move into open spaces, and avoid making unnecessary turns near the edge of the arena. When controlling Flowey, attacks should be combined so that one pattern limits movement while another targets the remaining safe area.

The game is designed as a simulator and fan recreation rather than a complete RPG. There are no exploration areas, inventory systems, dialogue routes, or character upgrades. Progress comes from learning the available controls, surviving longer, testing different attacks, and completing the recreated Omega Flowey encounter.
