Sentry KnightAuthor : Tyler Myers & Justin Wolf - 20 990 plays
Play as a sentinel posted in his tower keeping guard, and defend yourself against the mythical creatures trying to invade your land. Level up and divide your points between 3 skill trees composed of 48 devastating spells. Upgrade your weapons and defences to complete the game’s 8 levels. Defeat 4 bosses too, each with their own special powers. Shoot, burn, freeze and put your dexterity to the test to eliminate each wave of enemies. But take care not to hurt the sheep!
