Embark on a villainous adventure with Castle Doombad: Free to Slay, now available on iOS and Android! Grumpyface Studios invites you to experience the thrill of defending your evil lair from heroic invaders.

Assume the role of the nefarious Dr. Lord Evilstein and strategically deploy over 30 unique traps across 70+ campaign levels. Upgrade your defenses and thwart the persistent knights in shining armor who dare disturb your wicked plans.

Customize your evil lair with an array of "spoils"— wicked artifacts and ill-gotten gains—to create the ultimate villain's den. For a fresh challenge, dive into the roguelite mode, "Dr. Lord Evilstein's Roguevenge," where randomly generated levels test your strategic prowess.
