Reldens

The platform is built in NodeJS + MySQL, with Colyseus as game-server and Phaser for the game-client. It provides a lot of configurable features (https://www.reldens.com/features), and game contents management. 

The general idea is to allow developers to create everything from the administration panel, like: rooms (with or without gravity), objects (which can be almost anything, animations like doors opening, NPCs, enemies, etc.), items, skills, class paths, any kind of player attributes, and tons of other features like include audio and music. 

For now it's mostly oriented for developers the idea is to allow non-developers to be able to use it as well, reach the point where you only need to install it and use it without need to code. 

I've been working on this for a long time (started in 2018), so as you can imagine I'm dealing with quite some legacy code, but I'm improving it with every iteration. You can find it on GitHub: https://github.com/damian-pastorini/reldens
