ONLY UP Hard Platformer: For the Brave Climbers

ONLY UP Hard Platformer is not for the faint of heart. This version amplifies the difficulty with narrower platforms, longer jumps, and fewer checkpoints. Designed for players who found the original too easy, it transforms the climbing adventure into a true test of skill, timing, and persistence. The Japanese-inspired title hints at its extreme nature—prepare for a relentless upward battle.

As with all our games, it's completely free and runs directly in your browser. You can jump into this hardcore challenge without any installation. The controls are simple, but mastery requires practice and precision. Every mistake is punished, making success incredibly rewarding. Are you ready to prove your platforming prowess?
