About Isle Guard

Isle Guard is a compact tower defense game. Slimes, speedy runners, armored crabs and the occasional crowned boss march along a winding sandy path towards your island keep. Build towers on the grass beside the path to stop them before they get there.

Arrow towers fire fast at single targets, cannons hit whole groups with splash damage, and frost towers slow everything they touch. Earn gold for every critter you stop, upgrade your best towers twice, and sell the ones in the wrong place. Hold out for all 15 waves to save the island.

How to play

Stop the critters before they reach the keep. You start with 20 lives; most critters cost one, a boss costs five. Survive all 15 waves.
