Rules system?

[DiceWrangler]

Will this game be using a licensed (official) rules system, an open source system (including an SRD of a licensed system), a variant of something (like "based on" or "inspired by") or is it completely original? If published or a variant which system and version?

I was wondering this, just been told about this on steam and thought I would check it out and I've never heard of 2 of the races Rillow & Feldegug - and a quick google of them don't show anything. So no idea where it's from...

Anyone care to clear it up?

I think I saw devs mentioning that the world & lore(this includes races etc, I suppose) are completely original while role playing system is sort of original with some inspiration taken from D&D. But there seems to be no official FAQ or anything so this may not be a definitive info.

Black Geyser: Couriers of Darkness uses its own rule system. Even though this results in unique features, game mechanics are akin to those found in many other role-playing games. You start with character generation, gain experience points during gameplay and combat, allocate various things (such as skill points) at level-up, etc.
