One morning, Jack was torn from his ordinary life and trapped in a strange world.

Armed with nothing but an old pogo stick, he began his ascent through the mysterious dimension's unknown heights. In this realm where gravity behaves oddly and the ground is unreliable, Jack's only goal is to climb higher. But no one knows what awaits at the top—a way out or an even greater mystery? The only thing he’s sure of is that he’ll never find out unless he reaches the end.

One mistake is all it takes!

In Jack’s world, there are no second chances. With no save button or checkpoints, a single misstep can send you crashing back to the beginning. This unforgiving challenge will push your patience to its limits, testing your ability to bounce back—literally.

Overcome the unpredictable!

The world around Jack isn't just a backdrop; it's full of elements that can either help or hinder your progress. From unexpected aids that give you a boost, to traps designed to knock you off course, you'll need quick reflexes and a sharp mind to make it through.

Laugh, cry, rage—repeat!
