"Castle Doombad: Free to Slay - Take Revenge on Invading Heroes Now"

Defend your castle against would-be heroes
Embrace villainy in an all-new roguelite adventure
Customize your very own evil lair with unique spoils

Grumpyface Studios has officially launched Castle Doombad: Free to Slay on iOS and Android, a delightfully wicked twist on the tower defense genre. As the title boldly suggests, you’re no hero here—instead, you step into the boots of Dr. Lord Evilstein, the self-proclaimed master of menace, tasked with protecting your castle from a relentless stream of so-called "heroes" who just can’t respect your evil peace.

Take command of over 70 campaign stages, strategically placing more than 30 devious traps to stop armored knights, rogue mages, and other do-gooders in their tracks. Each victory lets you upgrade your deadly arsenal, ensuring your reign of chaos remains unchallenged.

But what’s a villain without a proper lair? Decorate your underground fortress with sinister "spoils"—twisted artifacts and stolen treasures that reflect your unique brand of wickedness. And when you're ready for a fresh challenge, dive into the roguelite mode, Dr. Lord Evilstein’s Roguevenge, where every run features randomly generated castle layouts, forcing you to adapt your evil strategies on the fly.
