It's a decent jigsaw game, however, it's hard to find where I'm supposed to put the pieces. This is because there is a stupid invisible border that I need to fit things to, within the wooden board where the pieces go.
The sensible, normal thing to do, would be to shrink the board and align the edges of the visible board and invisible border.
After fixing that, add a menu, and a gallery option, so I can see completed puzzles, and choose which ones I want to replay.
