About the game

A super-serious Rock-Paper-Scissors game, JMT DUeL. Rock-Paper-Scissors + Stats + Skills + Transparent AI Patterns. It will rewire your Rock-Paper-Scissors brain. Let's Duel!

Original Steam description

Placing paper dolls on a girl's sketchbook and recreating a brutal duel saga with "Shk! Thwack! Fwap!" mouth sounds.

※ No girl's sensibility. Dad-joke sensibility included. (Nobody around me to learn it from. T_T)

※ No girl's voice. Bone-dry TTS voice included. (We asked for a cute girl's voice. A robotic TTS came back.)

There is a tragic legend in this world...
Actually, it's not tragic at all. We just turned Rock-Paper-Scissors into a real 'Game.'

◆ Your Choices Decide the Game: <Stat Allocation>

Want to be a real man? Go all-in on Rock. If you're scared, invest in HP. But what if your opponent invested all their stats into Paper?!
The mind games have already begun against an unknown foe.

※ You can become a Gigachad, but it comes at a steep price.

◆ Legalized Cheating: The Last One Laughing Wins. <Skill System!!>

Unleash good skills, bad skills, and downright dirty skills matching each character's personality to make your enemies feel pure despair.
Attacking on a draw, forcing the enemy to repeat their hand, throwing punches before the countdown even starts—embrace your inner villain!

※ A true Gigachad who hits on a draw just to secure the win.

◆ We All Had That One Kid in the Neighborhood... <AI~ Habits>

Seriously, they exist. The classic kid who only throws Rock, or plays Rock-Paper-Scissors in strict order. But wait!
From simple habits to avoiding hands that got hurt, countering your last move, or picking their highest-damage hand—advanced AI patterns mimicking real human psychology await you. Read their mind and win. (Win rates are hidden, watch out for bluffs!)

※ She kept throwing Rock, but inside, she was playing 4D Chess.

◆ Choose Your Flavor: <Duel Modes>

[Classic Duel] : The raw, spicy taste of pure dueling! (No upgrades)

[Plus Duel] : The sweet taste of DPS brute-forcing! (Full upgrades)

◆ Wake up, Samurai... we've got gold to grind. <Upgrade System>

[Common Upgrades] : Standard reward boosts and base physical stats found in every game.

[Character Upgrades] : Standard unique stats and skill upgrades found in every game.

[System Upgrades] : Upgrading secret reconnaissance features to spy on AI patterns one by one—rarely seen in other games!

 ※ At the end of the day, this is Rock-Paper-Scissors. Trust your luck and gut feeling.

IT'S TIME TO DUUUUUUUUUUUEL!!!!!!!!!!!!!!!!!!!!!!!!!!!!
