I have updated the game again, with some new great features.
- More flexibility in the arguments for the custom difficulty level.
- The character for multiplication turned from * to x, because the original character had been getting confused with a period or the plus symbol (+).
- Window opens in center of screen instead of just the top left corner opening in center of screen.
- Typing anything with /say in it used to cause the command to do what the command does (print to the screen), but with the first five characters cut off. Now that is fixed, and /say has to be at the beginning of the text for the command to be valid.
