Dress-Up Traveller

One day, my sister challenged me to a game of Roshambo (Rock-Paper-Scissors-Hammer)! As her older brother, I couldn't back down from a challenge... but I decided to add one special condition.
The loser has to take off one piece of clothing. It’s a strip-match!

“The Traveler Cursed by a Succubus” is an RPG that features a marble-based turn battle system. All combat skills are represented as marbles, and players control the direction in which the marbles are launched to engage in battles and develop their characters. As characters level up, they acquire new marble skills, each with unique effects and possible combination effects.
