Play Mononinja and control a ninja through over 30 levels by accurately timing your jumps, dodging dangerous terrain, and reaching the exit at the end of each stage.

Don't let the minimalist 1-bit graphics fool you. Mononinja is a skill-based platform game where every mistake leads to failure and a fresh start. You'll control a tiny ninja navigating steep cliffs, deep pits, and narrow platforms using only a single jump mechanic. To complete each level, you must:
The game's unique feature lies in its one-button control system. Hold the button to charge your jump, then release it at the right moment to leap across the terrain. Holding it for too long will make the ninja overshoot the landing, while releasing it too early may cause the character to fall short. Although easy to understand, this mechanic demands excellent timing and precision throughout the game.
Like Stickman Boost, Mononinja gradually introduces its challenges instead of overwhelming players from the beginning. The early stages help you master the jump mechanic before presenting increasingly demanding platforming sections. As you progress, you'll encounter:
Each completed level feels rewarding because success depends entirely on your timing and control rather than luck.
Every stage revolves around mastering jump distance and landing accuracy. Follow these basic controls before applying additional strategies.
Hold the key or touch and hold the screen to charge your jump.
Release at the right moment to reach the desired distance.
Land safely on each platform.
Avoid falling into the abyss.
Reach the exit gate to complete the level.
Don't hold the jump button longer than necessary for short gaps.
Avoid rushing through consecutive jumps. Focus on landing safely before preparing for the next leap.
Observe the terrain carefully before making your first move.
Remember the jump strength that caused previous mistakes and adjust accordingly.
Stay patient during later levels, as a single inaccurate jump can send you back to the beginning.
