Master of the House

Four maids need rescuing, and the job falls to whatever monsters you can drop into a lane and point at the enemy. Pixel-art animation carries the payoff scenes, but the structure underneath is straight unit-placement: place, fight, survive the turn.

Between rounds you spend earned experience leveling up your units rather than recruiting new ones, so the loop is about building up what you've already placed instead of constantly restocking. Enemies come in waves, the maids are the objective, and the tentacled monsters you're commanding are as much a threat management problem as a source of the game's content. It's a tactics game first, with the adult material riding on top of the win condition rather than replacing it.
