🃏 Jevil Fight Online – A Deltarune-Inspired Boss Battle Simulator

Enter the chaotic world of Jevil, the secret boss from Deltarune Chapter 1, now remade into a smooth browser-based experience. Whether you're a fan looking to relive the challenge or someone practicing for the real game, this online simulator delivers a faithful recreation — no downloads needed, just pure action.


🕹️ How to Play

  • Control your soul with the arrow keys to dodge Jevil’s relentless bullet-hell attacks.
  • Use Z to confirm actions or attack, and X to cancel.
  • Two ways to win:
    • Pacify Route: Calm Jevil with Hypnosis and defensive timing.
    • Attack Route: Equip gear and unleash powerful moves like Rude Buster.

Playable on both desktop and mobile devices — built using Scratch, enhanced with TurboWarp for better speed and responsiveness.


🎯 Tips for Mastering the Fight

  • Learn Jevil’s moves such as Devilsknife, Ring of Spades, and Carousel to anticipate patterns.
  • Use defending to build up TP early and trigger key abilities.
  • The Pacify strategy requires careful TP and Hypnosis timing — great for those who prefer low-damage runs.
  • If going aggressive, upgrade weapons and use skills strategically to shorten the battle.
  • Don’t forget to stock up on healing items like ReviveMints and Spin Cakes.

Perfect for players who want to practice Jevil’s patterns or try different styles without restarting the full game.
