Great idea. Needs more design work
I love the concept of this game but it feels unfinished design-wise. *The dots in the circles need to be removed. I don’t care if it is an original tile or not. Just fixing this would make it much much more playable. * The colors in the bottom left box need to grey out or disappear when you’ve placed all one color, just like in your regular sudoku game. * Grey scale colors need to be used instead of green to represent neutral things (like the box backgrounds of other like colors in the game.) You can replace the grey pieces in the game with another color like teal. It has the potential to be an awesome game!
