What is Omega Flowey Fight Simulator?
This is a web-based fan recreation of the final boss battle of Undertale's Neutral Route. It simulates the jarring visual style, save-state glitches, and bullet hell mechanics of the original Photoshop Flowey fight.
Battle Mechanics
- Flowey Phases: Dodge a mix of finger guns, flamethrowers, vines, and flies. You cannot deal meaningful damage during these segments until his defense drops later in the fight.
- SOUL Phases: Periodically, the screen will switch to a minigame featuring one of the six human SOULs. You must survive their unique attacks until an ACT button appears. Pressing it calls for help, turning their projectiles into green healing items.
Tips for Beating Omega Flowey
- Prioritize Survival: Don't worry about the FIGHT button early on. Your only job is to survive until the SOUL phases trigger.
- Look for Warning Reticles: Red circles or exclamation marks indicate where vines or lasers will strike. Keep moving out of these zones immediately.
- Heal During SOUL Phases: After pressing the ACT button in a SOUL phase, grab as many green items as possible. This is your only way to restore HP.
- Stay Near the Middle-Bottom: During Flowey's main attack phases, staying in the lower center gives you the best reaction time to dodge falling nukes and sweeping flamethrowers.
- Don't Give Up: If you die, the game often fakes a crash or game over screen. Keep going!
Frequently Asked Questions
Is this Photoshop Flowey or Omega Flowey?
They are two commonly used names for the same boss form and fight. Players may search for either the Photoshop Flowey fight or the Omega Flowey fight.
Why is the screen glitching and faking errors?
This is a core mechanic of the fight. Flowey has 'stolen the SAVE files' and will use glitches, fake crashes, and sudden state loads to disorient you.
How do I heal in this fight?
There is no standard ITEM menu. To heal, you must survive a SOUL phase until the ACT button appears. Clicking ACT turns the hazard projectiles into green items that heal you.
Why am I doing 0 damage?
Flowey's defense is astronomically high at the start of the battle. You must complete all six SOUL phases to call for help, which permanently lowers his defense so your attacks can actually hurt him.
Does this simulator run well on older computers?
Omega Flowey is an extremely resource-heavy fight with many moving projectiles and visual effects. If it lags, make sure hardware acceleration is enabled in your browser settings.
Can I use a controller?
This web port is mapped to keyboard controls (Arrow Keys to move, Z/Enter to interact). You would need a third-party keymapper like JoyToKey to use a gamepad.
