Sunharbor Defense

Six harbors and 340 waves: 20, 30, 50, 60, 80 and 100 waves. Paired grids use 24×12, 28×14 and 32×16 cells in the same screen area. Odd missions have a few free barriers to help funnel ground units; even missions begin empty. Sand, pale green and pale red maps introduce more enemies, types and longer sustained attacks. Six weapons have six levels each, alongside route barriers and both field guides. All six missions are available during testing; completion records reflect actual play. Entrances and exits span 8, 10 and 12 cells for each successive pair. Only exit cells display arrows; entrances retain a subtle color band. Mission 1 has two 3-wide by 2-high bricks centered on the horizontal midline. Missions 3 and 5 have four 2×3 and four 3×3 bricks, respectively, aligned at the corners of a rectangle.

On mobile, Start opens the landscape layout automatically. Select a weapon from the persistent toolbar, then tap the map to buy and place; touch users can drag and release. Keys 1–7 select, Space pauses, and N starts the next wave early. Select an owned tower to upgrade or sell; upgrades stop fire. Buildings occupy 2×2 cells and must leave ground routes open; aircraft fly over obstacles. Each mission starts with 80 resources and 20 energy. Every escaped unit costs one energy. Both field guides are available from the menu and pause screen.
