Not so long ago I released an early version of Osnowa — an open-source roguelike framework for Unity which emerged from games I've been making for a few years.

Most features of Quinta essentia and Artifex gladii were made by the tools and code which are now available for free as a part of Osnowa.

If you want to make a roguelike in Unity, you're welcome to check it out! Moreover, I'd be happy to see contributions to Osnowa made by other developers.

It's available here:

If you decide to make your 7DRL with it, I offer my support before, during and after the challenge.
