Lewd Dungeon Manager

You play the Dark Lord, and your job is keeping a dungeon standing against waves of heroines who keep showing up to knock it down. It plays like tower defense and RTS bolted onto a visual novel, which is a stranger combination than it sounds.

Between attacks you're laying traps, positioning monster units, and pouring resources into upgrading the place so the next wave doesn't wreck what you built. Energy management sits underneath all of it, so every defense you queue up costs you something you'll want later.

The writing leans into humor and the occasional meta joke rather than playing the evil-overlord premise straight, which keeps the strategy side from feeling like homework.
