Choose a square. Click no-square place: create square. Click a letter (keyboard working now!) to enter it to the red square. (square filled black means space) You can always change the selected (red square) square. Just click a black square. Remove square: select a square and click it again. Click up arrow to show the copy list and down arrow to hide. If the crossword words all are about Scratch, you can post it is comments. I will add it to "Scratch Crossword Game". (This run like "My World")
Update Log: 27-04-2021 - Added Keyboard-Entering Function (enter letter by using keyboard). At the same time, space is same to the open-copy-list key so the open-copy-list key changed to up arrow. (I don't know why key C is not available) -------------------------- All by me.
