I was drawn in by the title and visuals, and stayed for the intriguing story and unusual mechanics.
Congrats, the game feels complete, polished, and well-crafted. Despite some initial difficulty in understanding the mechanics, we managed to exorcise all three husbands in the end!
Everything is well done: from the graphics, animations, fonts, and music to the care put into the game page. Really original mix of positioning, guessing, turn-based play, and wave alignment.
You should definitely consider releasing a full version!
