Hello everybody,
We are proud to present Rift's Cave now supports Linux OS! If you would like to test with us, just log into Steam from a Linux OS then download and play Rift's Cave! All bugs should be reported here.
We are working very hard to continue adding more support for each system in the future so that more users are able to experience our game! Please be patient and we will eventually have more support for more systems in the future.
Thank you all for supporting Rift's Cave!
