"Space Reaction" is a simple game for two players. The goal of the game is to collect three crystals before your opponent does. The first player to collect three crystals wins the game. To collect the crystals, you must either reach your opponents crystal before they do, or make your opponent immobile by winning a duel.
Speed is crucial in this game. You must be quick to press the various buttons that appear on your side. Whoever presses first reacts first. The buttons then disappear for a second and reappear at a different point on your side.
So, be fast and press first. Have fun!
