JEU De Jongles

You control a red square, moving it left and right with your mouse. The goal is to keep a single ball in the air by bouncing it off your square, like a one-player juggling act. The mechanics are minimal; you just track the ball's arc and position your square underneath it. The pace starts slow but the ball gradually gets faster, making you react more quickly. It feels focused and a little tense, a test of simple concentration.
