RNGremlin is a dice rolling application with a pixel art aesthetic intended for use with solo TTRPGs but isn't necessarily limited to that use case. It was originally built using Godot 3.6 in order to support older hardware for anyone making use of a repurposed laptop, etc. but has been converted to Godot 4 in preparation of being packaged for flatpak.
