Fun and challenging puzzle game with an impressive number of boards. Would benefit aesthetically from the option to have a small black dot instead of a big ugly red X. And on completing the puzzle these marks should all disappear so the clear solution can be viewed and enjoyed. And some puzzles have redundant rows or columns, which could be programmatically removed.

Ok, I love this game but it desperately needs a few features. 1: Show the grid size on every level. When levels change and suddenly the grid is 1 square wider, or 1 square shorter, it makes it really tedious. Just show it as a little number on the edges etc. 2: When using multi-select, the Undo feature should undo the entire selection. Selecting 27 squares only to accidentally press the wrong icon feels very clunky to backtrack. And, it's not always easy to remember how far back you need to undo
