I am starting to give out keys for the closed beta of Settler's Domain!
The beta has all the intended content that the full release will have, but it's still very rough around the edges (it needs balancing, UX improvements, finished game sprites, bug fixes, etc).
If you want to playtest the beta, join the Settler's Domain Discord server and request a key: http://discord.gg/qFDtxMm57F
