Building a roguelike from scratch takes months. This engine gets you to a playable prototype in a day.
You want to ship the next Nuclear Throne, Enter the Gungeon, or bullet-hell roguelike - not spend your first three months writing a character controller, an AI state machine, and an inventory system, or untangling a 200 MB general-purpose framework where your genre is one demo scene out of ten.
Top Down - Rogue-like Engine is specialized. It does one thing: top-down action roguelikes. Every system the genre needs is included, already connected, and configured entirely from the Inspector. Open the demo scene, press Play - you have a working game. Swap the art, tune the numbers - you have your game.

🛠 ONE WORKFLOW FOR EVERYTHING
─────────────────────────────────────
Every system follows the same pattern: create a ScriptableObject → assign it in the Inspector → done.
- No boilerplate, no architecture decisions, no hidden dependencies.
- New weapon, enemy, ability, item, or dialogue - minutes in the Inspector, zero code.
- Need custom behavior? Inherit one base class to add your own weapons, abilities, AI states, or actions. The core stays untouched, so updates never break your work.

✅ WHAT'S INCLUDED (All systems are described in the documentation)

🔫 Weapons
- Ranged weapons with multi-shot, spread, recoil, and burst fire. Bullet-hell ring and step-based attack patterns. Melee weapons with slash, thrust, and dash modes.

💬 Dialogue System
- Node-based visual editor with drag-and-drop branching conversations. Typewriter effect, player choices, and an action system to trigger in-game events (give items, start quests, unlock doors).
🎵 Audio System

Waveform preview, per-sound cooldown, fade in/out, spatial blend, and clip variance. Dedicated music player with sequential/random playback, crossfade, and gap between tracks. All configured via Scriptable Objects, no code needed.

The WebGL demo is built 100% with this engine, using the same prefabs and ScriptableObjects you get in the package. What you play is what you ship.

⭐ If this engine saved you time, a review helps a small specialized tool stay visible next to the big general frameworks - more than you'd think.
