🃏 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.
