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
