So you have found a link, but the school firewall says “Game – Blocked.” Here is a safe, ethical workaround that does not require hacking or VPNs (which often get you detention):
Use Google Translate as a Proxy: Go to Google Translate. Set “Detect language” to English. Paste the URL of the unblocked game site into the text box. Click the translated link. Google serves the page from its own servers, bypassing many filters.

| Phase | What happens | What to do | |-------|--------------|-------------| | Start | Flowey attacks with lasers, hands, bombs, and spinning circles | Dodge as best you can — your HP will keep refilling | | Soul modes | Switches between red, green, blue, purple, yellow, cyan | Adapt quickly: green = block, blue = gravity jumps, purple = tightrope, yellow = shoot | | The “FIGHT” button | Normally does nothing except 1 damage | Keep pressing it — every hit matters | | Soul containers | After taking enough damage, Flowey destroys your Mercy/Act/Item buttons | Don’t panic — you only need FIGHT | | The save souls phase | 6 souls (Toriel, Papyrus, Undyne, Sans, Mettaton, Asgore) appear around the bullet board | Touch each soul repeatedly while dodging — they heal you and refill your options |

Don’t Panic at 1 HP: You cannot die in Phase 1. Literally. Flowey will drop you to “1 HP” and then mock you, but the killing blow never comes until the soul phase. Use this time to learn patterns.
Memorize the Soul Orders: The souls always appear in the same order: Cyan → Orange → Blue → Green → Yellow → Purple. Know what is coming next.
The Green Soul Shield Trick: When you have the green soul, hold the shield continuously but tap the direction keys to move between the gaps of the flamethrower. Do not drop the shield.
The Yellow Soul Aiming: Your heart turns into a crosshair. The hitbox is actually the tip of the heart, not the center. Aim slightly above the pellets.
The Final “FIGHT” Spam: When the souls form the star, do not click slowly. Mash the “FIGHT” button as fast as possible. Speed determines how many times you hit him before he reforms.
