Version 1.93 brings a big update to the Puzzle Solver used in the Editor. A Picross Touch player by the name of Patrick Hogg decided to write a picross puzzle solver for fun. He then contacted me and provided me with the source code to his solver. His implementation is so efficient that it allows for larger puzzles to be validated.
He allowed me to use his code, and I implemented it into Picross Touch.
Full changelog:
Make sure to set your FPS Lock option to 240 for larger puzzles. This will provide much more fluid drawing.
Please report bugs if you encounter any. Thanks.
