JUMPER is a hardcore physics-based game built around a single action: jumping.

You stand on a jumper — a spring-powered device with a single point of contact.
You don’t walk.
You don’t run.
You only jump.

Every jump is determined by your orientation at the moment of contact.
Once the jumper’s foot touches the surface, you lose the ability to change anything.
There is a brief pause — just long enough to realize your mistake.
Then the jump happens.

This game is about accepting irreversible consequences.

There are no upgrades, no checkpoints, and no progression systems.
One level. One tool. One rule.

Your goal is to reach the endpoint without touching the ground with your body.
Falling means losing height.
Losing height means repeating your own mistakes.

The challenge is not reaction speed, and not mechanical precision.
It is the ability to make a decision — and live with its outcome.

You are always in control.
Until it’s too late.
