Joy Jump is a simple two-level reflex game built around timing and focus. The gameplay is based on interacting with a moving square within a limited time period.
The first screen introduces Level 1, where a square moves across the screen at a moderate pace. Each successful tap on the square adds one point. After completing the first stage, the game continues to the second level automatically.
Level 2 increases the pace and reduces the size of the square, making its movement faster and less predictable. This stage requires more precise timing and attention as the square changes position more frequently.
A full session includes both levels, forming a complete Joy Jump run. The score reflects the number of successful taps throughout the session. The design focuses on clarity, short sessions, and consistent mechanics without additional elements or distractions.
