This game is similar to many io projects, but has an interesting feature. Here you can move only in 4 sides - up, down, to the right and to the left. On the one hand it does complicate ways of the attack, but on another it helps to calculate ways of retreat.
You begin the game playing for a triangle, but after each victory you will receive one additional edge. For example, playing for a triangle and having destroyed the rival, you will become a square and so on. The gameplay is quite simple, but it can attract you for hours.
Control: move in the game via W A S D keys and shoot using the left mouse button.
