In this game, recognize the number of sides in the polygons that come up quickly. Press the correct number button on the keyboard if you find a polygon of that number of sides. For example, pressing 3 would score points for a triangle. If you find a 10-sided polygon, press 0. The number of keys that you can press through the game is limited to 80 keys. The number of keys remaining is displayed. There is also a limit of 160 polygons. The game will be over when either limit is reached. More points are earned for shapes that have more sides. More points are also earned if the shape is closer to the top.
The polygons were made with the pen and then uploaded as sprites. The backdrop was done similarly. Everything else was made with the Scratch paint editor.
