I have purchased nearly every game by this developer and enjoy the approached of solving a puzzle for the fun of it. I didn’t buy this one for quite sometime thinking it would be like sudoku and continuously rechecking the numbers to see what is missing, it is not. It is delightful. How about the same concept but with words? That would be enjoyable too.
I own all of your games. Keep up the great work!
Very easy in the beginning and then progressively gets more difficult. Nice to have a new puzzle by this developer.
A quick puzzle game that feels tactile and responsive - except I'm almost sure 33 is missing a piece. It'd be good if there was a way to skip a level or two ahead, too.
