I liked the sounds and visuals, but honestly, I didn't understand anything. I just kept changing the same cell over and over again, pressing 1, 2, 3, and eventually won.
I'll try and figure out how to make the game more intuitive. You just sort the blocks into the colored columns, But you can clear blocks by row, column, or even diagonally if all the cell match in the corresponding blocks.
Thanks for trying my game! I appreciate the feedback.
