Space Is Key is a famous reflex game where you only use one key to survive: the Space key! It sounds simple, but don't let the simplicity fool you.
Your mission is to control a small square that moves continuously in an environment full of obstacles, narrow gaps, and sharp barriers. The ultimate goal is to go as far as possible!

The gameplay is extremely simple; you just need to press the Space key to jump over all obstacles. However, to master it, you need to observe further, feel the rhythm of the movement, and always stay focused. You have to jump early on some hurdles and late on others. Sometimes you have to do a lot of jumps in a row with great accuracy.
The challenge intensifies with speed, necessitating rapid reflexes. Avoid clicking randomly, keep a steady rhythm, and take a break if you fail too many times to win the game.
As the squares start sliding across the track, you need to watch for height, distance, and speed. Jump high enough to get over the wall, jump early for wide gaps, or late for low thresholds. Keep your rhythm so you don't get confused when encountering multiple traps. A millisecond's mistake will blow you up into pixel dust.
