About this game
Night falls over the islands and the sea is coming for your lighthouse. Rowboat swarms, armored galleons, invisible ghost sloops, healing jellyfish and a kraken that grabs your towers all sail the channels toward the light. Hold the line.
Tidewatch is a hand-drawn tower defense game made for one-thumb play. Tap a rocky build spot, pick a tower from the radial menu and watch cannonballs arc, harpoons fly and fire burn across the waves.
Your lighthouse fights back
Drag from the lighthouse to sweep its beam across the sea. Every ship it touches is stunned, and hidden ghost ships are revealed. Time your sweep for the moment a swarm bunches up or a boss closes in.
Five towers, ten specialisations
- Harpoon Tower: strong single shots that also hit flying gulls
- Cannon: arcing splash damage for crowded channels
- Bell Tower: slows ships and reveals invisible ghosts
- Kelp Trap: roots ships in place
- Fire Brazier: burn damage over time
Each tower has 3 upgrade levels, then a choice of two specialisations: Whaler or Twin Reel, Mortar or Grapeshot, Storm Bell or Choir Bell, Strangler or Tangle Field, Wildfire or Blue Flame.
Eight islands to defend
- 12 to 16 waves per island, from Gull Rock to Leviathan's Maw
- Two-lane maps, a split channel and a tidal map where the path changes when the tide flips
- 9 enemy types including flying gulls, splitting powder barrels, fast crabs and two bosses
- Earn up to 3 stars per island by keeping your lives
Play your way
- Three difficulty modes: Calm, Normal and Storm
- Endless mode on every island you have won
- A new daily challenge with a twist every day
