About This Game

In Idle Jumper, you control a tiny slime who jumps forever—your task is to help them reach new heights by unlocking upgrades, managing momentum, collecting coins, and discovering new power-ups. Whether you prefer an active playstyle filled with strategizing each move, or a more relaxed idle approach while watching your character improve over time, Idle Jumper grows with the way you want to play.

As you progress, you’ll earn resources to invest in permanent upgrades, boost your jumping power, unlock new modifiers, and automate mechanics to increase your long-term efficiency. Each run becomes more powerful than the last, letting you soar past previous milestones and discover how high you can climb.
