I've worked on things other than games, too. This is the miscellaneous software I've had a hand in since the start of my experience in development.

SyndiBox (GDScript)

SyndiBox is a text dialog engine I created as an addon for the Godot game engine. The purpose of this addon is to allow dynamic, custom text for games that heavily depend on dialog, such as RPGs and visual novels. Published in September 2019, it has received 39 stars, 13 releases, 8 forks, and 5 contributors in as little as 9 months. SyndiBox is free and open source under MIT license.
