About Firework Master: Idle Merge
Merge to grow. Grow to change the sky. Become the Firework Master who guards the Han River night! An idle merge RPG where you defeat the yokai swarming the night sky with fireworks. Drag the shells scattered across your workbench together, and sweep the monsters away with bigger and bigger bursts. ◆ Fireworks that get grander as you merge Overlap two identical shells and they become one tier higher. From a tiny Ember through Peony, Chrysanthemum, Willow, Butterfly and Phoenix, past Supernova to Nebula, Binary Stars, Black Hole and the Big Bang - and beyond to Aurora, Comet, Galaxy Cluster and Infinity: 20 firework shapes across 100 tiers, and every tier paints the sky differently. ◆ A wall to break through every stage The yokai don't stand still. They pound your barge, shrug off hits behind armor, and hide Big Bursts in darkness. Each stage shows you its condition on screen — see what you need to raise, and upgrade it. Raising just anything won't get you through. ◆ 30 bosses, one ladder Challenge them whenever you like. Every first clear permanently raises the grade of the shells you craft, and beyond the Lord of Night, new bosses from beyond the stars - the First Darkness waits at the very top. ◆ It grows while you're away Your Master crafts, fires and merges shells on their own. Raise Auto Craft, Auto Merge and charge speed, then go about your day. When you come back, your Gold has piled up. ◆ A fireworks show that uses the whole night sky The heat builds as you fight. When it's full, it's showtime! Every shell you've made launches into the sky at once. The higher and more numerous your fireworks, the more spectacular it gets. ◆ Pals who fight beside you Spark Drone, Drumming Tanuki, Shield Turtle, Lantern Fairy, Lucky Cat, Shooting-Star Dragon, Fire-Arrow Hawk, Moonlight Whale and Starlight Tiger. Welcome them with Festival Tickets and raise them, and their looks evolve too. Awaken a maxed-out Pal with shards to make it even stronger. Every Pal's odds are shown in the game under “Pals tab → View Odds”. ◆ Things to do today Daily check-ins, daily missions that change every day, and the Grand Festival, a 30-second all-out blast. Even a short visit has something for you. ◆ Start over, stronger Rebirth to earn Starlight. Each Starlight permanently raises your firepower and Gold. Boss clears, Secret Arts, Pals and awakening all stay with you. ― ― ― • No ads pop up on their own — you watch an ad only when you choose to, to earn a reward • Play offline (watching ads for rewards and making purchases need a connection) • No sign-up, no login — we don't ask for your name or contact details • A small download that opens right away Privacy Policy: https://firework-master.web.app/privacy-en Support: https://firework-master.web.app/support-en Contact: [email protected]
