Your objective is to guide a small square from the left side of the screen to the right by pressing the spacebar to make it jump. The game is a test of timing and reflexes, as obstacles like walls, spikes, and moving barriers will instantly end your run if you collide with them. Each level introduces new patterns and faster speeds, requiring precise input to succeed. As a beginner, focus on learning the rhythm of each obstacle sequence; the key is to press the spacebar just before your square reaches the hazard. The challenge escalates quickly, so stay calm and try to anticipate the next jump rather than reacting at the last second. In tense moments, concentrate on the gap you need to pass through and time your press to match the square's movement. The core gameplay loop is simple but demanding, with success depending entirely on your ability to master the timing for each unique level layout.
