Play as Marty, a hopelessly clumsy college student with a... big problem.

A blessing — and a bulge — far beyond the limits of ordinary trousers.

Only Defense is a spicy and absurd visual novel adventure filled with over-the-top characters, unexpected choices, and scenes that’ll make you laugh, blush, and question your life choices.

There’s tower defense action too, sure — but at its core, this is a story about trying to survive college when your “tool” becomes the most wanted magical resource in town.

• 💬 Make choices that shape Marty’s fate
• 📚 Fail (or ace) bizarre skill checks
• 🧪 Meet seductive witches, intense professors, and book-hungry vampires
• 😳 Try to hold your dignity... and your pants

This demo is just the beginning! It's unhinged, unfiltered, and unapologetically horny.

Your feedback means the world to us — it’ll help us make an even wilder, sexier, and more hilarious game.
