Angel Engine — a development tool for browser-based and cross-platform MMORPGs: a map and data editor, with a single project for both server and client.

In this video: base (NPCs, items, skills, projectiles, classes, resources, quests, animations, variables), tiles and layers, auto-tiles and animated water/waterfall, PNG layers and mask-based collisions, merging maps into an open world, map attributes, trees and fishing, combat and NPCs (including NPC vs. NPC), a simple event with dialogue and a quest, building a server / PC / web / Android version from the editor, and multiple clients simultaneously.

The engine is under active development—the interface and features are subject to change.
