Love the idea, but I don't understand it at all. Where's the clues? Boxes aren't numbered. Why are there input text fields? Why is the crossword filled out already? I've never seen a puzzle with only seven or fewer boxes in any direction. If working, would need to see a version with at least 12-15 boxes across and down.
