It would be better if I could set red or blue with one click rather than having to cycle through. Some UI like this, where X is Red and O is blue:
_______
| \X|
| \|
|\ |
|O\_____|
```````
Tapping the red or blue corner of an unset gray tile would would set the tile to the tapped color, and tapping a red or blue tile would unset it back to gray.
Also, the "fixed" tiles of the puzzle need to be presented in a different style from the "dynamic" tiles the user can set.

Is there a GitHub repo for this?
