Today’s Amazon Free App of the Day is Castle Doombad (4/5 stars, guidance suggested, FREE today only), from Adult Swim.
Dr. Lord Evilstein has kidnapped a princess, and now his evil lair is crawling with do-gooders. In this reverse spin on tower defense it’s your job to defend your home turf from heroes trying to save the day.
View your domain from a side-view perspective, placing traps and unleash minions on your unwitting foes to protect the fortress. Touch and drag up and down on the tower to navigate floors. Across three chapters and 45 levels you’ll outwit intruders that attempt to invade your castle from all sides—ladders allowing them entrance on higher floors, underground drills to start on dungeon floors closer to your fair maiden.
Keep the princess safely in your clutches and send those heroes cryin’ back to momma.
