SlimeStorm

SlimeStorm is a professional danmaku (bullet hell) design tool that lets you create various types of danmaku patterns without writing any code. It is especially well-suited for Touhou Project-style danmaku. SlimeStorm supports multiple emitter types including bullets, lasers, visual effects, and enemy aircraft, and with its rich event system, you can achieve complex danmaku patterns.

Key Features

• Graphical editing interface with a structural tree for intuitive danmaku project editing.

• Property panel-based parameter editing for quick adjustments and batch modifications.

  

• Separation of danmaku player and editor, making future expansion easier.

  

• Graphical texture selection tool for fast access to sprite assets.

  

• Complex danmaku logic powered by an event system.

  

• Timeline editor for rapid level danmaku pattern arrangement.

  

• Steam Workshop integration for quickly sharing your creations with others.

  

• Built-in Player with outstanding rendering performance, easily achieving tens of thousands of bullets on screen at the same time.

  

• Built-in auto-dodging AI. Creating hellishly difficult bullet patterns to torment the AI can be surprisingly fun.

Additionally, this software provides a danmaku file data interface that supports integration with game engines such as Unity and Godot, and is also compatible with .NET projects.

The Danmaku patterns of the following games were created using this editor. With this software, you can view the Danmaku files of these games and feel free to learn from them or modify them to your heart’s content. (Search for the UserBarrage folder or .brg files within the game folder.)
