A rogue-lite tower defense where you build, cast spells, and fight as the king himself. Choose your crossbow, shape your deck, and survive endless waves — every run a new strategy.

SteamAbout To Def Or Not To Def

A skeleton army has appeared from… somewhere.
Build towers, cast spells, fight beside your defenses, and keep them away from your castle.

Yes.
Merge towers into stronger versions, combine cards and spells, and create a different build every run.

Made by One Developer
I’ve played far too many tower defense and roguelite games, so I made the one I wanted to play.
If you want active combat, tower merging, and chaotic builds, you’re in the right place.
Build. Merge. Fight. Defend.
