Ember Detour

Place or reclaim ten walls to route enemies from S to G without sealing the path. The dotted shortest route is shown. Each tower attacks every route cell within two orthogonal steps; selected tower coverage is outlined. Damage uses tower level, and the next wave halves one listed tower type. Select a tower and spend 2 cores to upgrade it, or repair 4 gate integrity for 2 cores. Two cores are earned after each surviving wave. Preview the exact gate damage before sending each of five waves. A long route outside tower range is not automatically safe.
