What is Defense of the Oasis?

This single-player, 2D strategy game follows your efforts to reunite a kingdom across procedurally generated levels. You spend 85 turns uncovering tiles, finding cities, building roads, and researching technology before barbarians attack. If your cities survive and you find the level's Glyph of Power, you claim it; collecting twelve glyphs across different levels wins the game.
