This is a very basic Tumbleweed editor, with nothing fancy like capturing rules, lines of sight etc. It just has the ability to play red/white hexagons, by default of stack size 1. There are a couple of keys that will change this default listed below
Pressing the number keys 1-6 will change the stack size from 1-6.
Pressing the number key 7 will change it to red's turn.
Pressing the number key 8 will change it to white's turn.
Pressing the number key 9 will change to placing the neutral (grey) two stack, which could be useful for resetting the board.
Pressing the number key 0 will allow you to clear hexagons of color/stacks.
Pressing the shift key once will stop the color from changing after a placement, while pressing it a second time will toggle back to alternating colors.
