How do you do you save a game on Sonic Robo Blast 2

First make sure that your character is standing still somewhere in the level and that the camera is not moving. Then press the Esc key and go into 1 player. After that click save and select the file you want to use on the save screen. Enter a name for your file by typing, and then press enter. If you save at the beginning of a level, make sure that the introduction to the level you are in disappears. The reason why I told you to make sure of all of that is because glitches will result if you don't. I know this cuz it happened to me once.
