Great game but....... – Hidden Scenes - Winter Wonderland Review

Just discovered this type of game and it is wonderful. However, I do have an issue. When you play, then leave the game, then return, the menu states “19 out of 20 games completed”. This is probably a real stupid question, but how can you tell what level you haven’t done? At first I thought the colored pictures have been done, with the black and white ones left to do. Nope, that is not right. There is no way to contact the developer other than writing a review, so here’s hoping this is the way to contact them.
