This game was basically dead, but the dev work was apparently transferred to some volunteers. They put out a huge update, put it up for sale at -94% until March 5th and enabled EAC support for Linux.
Hoping to get more people to play this and keep it alive.
Why it fall flat and lose player in the first place?
The old devs kinda stopped adding new stuff and fixing bugs. The current ones did that and also seem to have a bit of a plan for how to keep things interesting. More gamemodes and UX improvements are a big point of improvement too according to old time players. Its absolutely possible that it will go down again, it just kinda depends on the community staying interested and giving feedback, but at that price it wouldnt be a huge monetary loss even if it does die down again.
