Thanks Baiten!
This already is it's own game outside of any modding community. It's being made with the Unity Game Engine same as Legion TD 2 the tower defense game you are referring to. I've actually been talking to the dev of LTD2 recently, he just got his game to Alpha!
Sheep Tag 2 still has ways to go but you can follow along in our discord:
