# Undertale Style - RPG Template | Summer Engine

## About this template

Undertale-style games rewrite RPG rules: every enemy can be spared through unique interactions instead of violence, battles use bullet-hell dodge mechanics where you move a soul through projectile patterns, and choices permanently affect the world across genocide, pacifist, and neutral routes. The game breaks the fourth wall with meta narrative that references save files, resets, and the act of playing itself. Retro pixel art carries expressive characters through memorable boss fights where each enemy has completely unique attack mechanics. Humor sits right next to genuine heartbreak.

Summer Engine helps you build the mercy/fight combat system, bullet-hell dodge patterns, route tracking, and fourth-wall narrative through conversation. You define the characters, the world, and the consequences. The AI constructs the battle mechanics, enemy encounter designs, and branching route logic.

What makes this format powerful is that the game responds to the player as a person, not just a character. Kill everything and the game judges you. Spare everything and the game rewards your compassion. Reset and the game remembers. Players feel genuinely responsible for their choices.

## Who it's for

* Narrative designers who want player choices to have permanent, meaningful consequences across multiple routes.
* Solo devs inspired by Undertale and Deltarune who want to build a game that subverts RPG conventions.
* Designers who love bullet-hell mechanics and want to combine them with RPG storytelling.
* Creators who want to build a meta narrative that breaks the fourth wall and acknowledges the player directly.

## Highlights

* ### Ruins Demo  
Build the opening area: teach the spare mechanic, introduce the bullet-hell dodge system, and establish the tone with a first boss who tests mercy.
* ### Boss Fight Showcase  
Create 3-4 boss encounters with unique bullet patterns, spare conditions, and dialogue that changes based on whether the player has been killing or sparing.
* ### Full Route Game  
Develop a complete RPG with pacifist, genocide, and neutral routes, each with unique content, endings, and meta consequences for replaying.

## Highlights

### Mercy or violence

Every encounter offers both options. Spare enemies by understanding what they want. Fight them and the world gets darker. Both paths have full content.

### Bullet-hell dodge combat

Enemy attacks are unique projectile patterns the player dodges in real time. Each boss has completely different mechanics and visual themes.

### Permanent consequences

The game tracks every kill and every mercy. Routes diverge based on cumulative choices. Some consequences persist across save file resets.

### Fourth-wall meta narrative

Characters address the player directly. Save files become plot devices. The game remembers previous playthroughs and reacts to resets.

## Features

* ### Fight/spare dual combat system  
Each enemy has unique spare conditions (compliment, flirt, hum, pet). Fighting works but changes the route. ACT commands reveal personality.
* ### Bullet-hell defense phase  
Player controls a soul in a box, dodging enemy-specific projectile patterns. Bones, spears, fire, musical notes: each boss has a visual signature.
* ### Route and consequence tracking  
Kill counter, mercy counter, and specific enemy survival flags drive three major routes with distinct story content, dialogue, and endings.
* ### Meta save system  
Save points are diegetic. The game detects resets, tracks previous runs, and characters may reference past playthroughs in dialogue.
