Deltarune Fight Simulator

How to start

A Deltarune fight in the full game gives the party FIGHT, ACT, ITEM, SPARE, and DEFEND, and the SOUL dodges inside a bullet box. This simulator is the dodge: move the heart and last as long as you can.

1. Press Play, then click the battle so the keyboard reaches it.
2. The title reads BATTLE SIMULATOR V3. Choose Desktop (keyboard controls) or Mobile (touchscreen controls). The prompt says click to select.
3. The main menu lists Start Game, View Leaderboards, and Save/Load Game. Arrow keys move, Z selects, and X goes back.
4. In the battle, the arrow keys move the SOUL. The screen keeps a difficulty label, Kris's HP, and a timer in seconds.

What the battle asks you to survive

Scube3000's instructions list four difficulties: Easy, Medium, Hard, and Hardest. The background song changes with the difficulty, and the project includes three songs. An update on the Scratch page says Ralsei and Susie will judge you. The same page lists save files.

The notes name the enemies in the project: Rudinn, Rabbick, Lancer, Rudinn Ranger, Clover, Jigsawry, Ponman, and Jevil. Jevil is the Hardest-only enemy. The separate Jevil fight on this site is tripoid's full battle, with ACT commands, rather than this survival timer.

DEFEND in DELTARUNE reduces damage and fills the TP meter. Ralsei's battle lesson says simply defending makes the attack hurt less and gathers TP. This simulator does not ask you to pick that command. You steer the SOUL for the whole round.

Boss battles after this one

The grid under this guide collects the other battles on the site. Spamton NEO is the long Chapter 2 secret-boss page, and the one to open for a Spamton NEO fight simulator. Jevil is the Chapter 1 secret boss. The Chaos King and Lancer are the Chapter 1 card bosses. The Chapter 3 Knight is the later boss. The Black Knife plays that Knight battle again, for the weapon that loses a shard. Gerson is the Chapter 4 hammer, and the project covers about 12 of 21 turns. Sans is an Undertale fight, in Japanese, from the Genocide route's last corridor. Undyne the Undying is the Genocide heroine, a full fight. Omega Flowey is the Neutral Route boss after Asgore. Asriel Dreemurr is the True Pacifist finale. Asgore is the king at the barrier, fire and trident. Mettaton EX is the CORE ratings show. Bad Time Simulator is jcw87's English take on the Sans duel. Undertale Yellow's Flowey is that fan game's Meta Flowey fight.

How to last longer

This project is a survival timer, not a command menu. Arrow keys move the heart the whole time. On the menu, arrows move, Z selects, and X steps back. The opening prompt is Desktop or Mobile. Mobile draws a D-pad the author calls a beta. Desktop is the reliable set.

In a real Deltarune battle, passing close to a bullet without touching it outlines the heart in white and adds TP. On some attacks that graze also shortens the enemy's turn. Aimed shots are easier if you creep: they were pointed at the place you just left, not the place you are going.

DEFEND, in a normal Deltarune fight, banks 16% TP immediately and cuts that turn's damage by about a third. Scube3000's simulator never asks you to pick DEFEND. You only steer.

• Hardest is the difficulty that brings Jevil out. The other three settings are Easy, Medium, and Hard.
• When a Jevil volley is aimed at you, sit near the middle and nudge after the shots have already picked a line.
• Spade spirals are the graze turn. Looping them fills TP faster than parking in one gap, if you can spare the precision.
• The Scratch page talks about cloud leaderboards. This packaged copy keeps those scores on your own machine. A number you post here is not a worldwide ranking.
