nice, I haven't seen anything like this before
An alright little education tool. Nothing more, nothing less.
SWEET!!! Very awesome to be able to make picross puzzles, and I think I'll be using this for printable goodies! My only complaint is that the top row is kinda hard to click on (I had to click the very very very bottom edge of the top row). Otherwise, amazing job, especially as a test of your skills!!
Oops, you're right. Thanks though! The top row should be any easy fix, and if I can find the time I'll try to make an option to view in printout format
Monday Edit: Fixed and added an export button to save as a jpg
