Main features of Radial+ for Windows 8 and 8.1:
When you install and run the app, you will be presented with the main screen of the app itself which can be seen in the screenshot below.
Simply tap on the Play button in the above screen, and the gameplay should start. The gameplay screen is shown below.
In the above screen, the small sized blue block that you see at the center of the screen is the block which has to be rotated with respect to the circular rings which are rotating around this block. The circular rings rotating around the block are constantly decreasing in diameter so they will eventually collide with the block if it isn’t aligned properly with the opening of these rings. You can see the score at the center of the screen in the green circle. The score corresponds to the number of seconds that you have survived in the game. When you collide with the rings, it’s game over and you will be shown the game over screen along with your score.
This sums up the main features of Radial+ for Windows 8 and 8.1.
