Game got updated with Linux support on original release in 2016.

Two years later Linux support has been discontinued. By the words of developers team was "too small to support PC Mac and Linux versions". So Linux version been discontinued. No refunds been provided to linux users. Instead developers offered Linux customers to keep playing older Linux version, leaving them with no updates.

Devs "appreciate frustration of community".

Mac and Linux versions are available and are first-class citizens!"
