I can't find in the store

Multiple times now I've been forced to do the same puzzle over again. After it happened the first time I thought it was perhaps because I hadn't done both puzzles on the same "wall", but no it just saves incorrectly even when I advance to the next puzzle before I exit. Whether I've solved a puzzle or not is an all-or-nothing affair, how could you even screw this up? Am I the only person to stick with this game long enough to even notice/report it?...

I know you (The Dev team) have stated that you don't plan to add achievements to your games. Personally I would love to see achievements in these games and I believe you are missing out on the achievement hunter market. Achievement hunters very much like lower cost more casual games for a fun and relaxing 100% between their normal huge grinds. I sincerely hope you reconsider adding achievements and corner some of the achievement hunter market. Just one guys opinion thanks for your time....

I got this recently & enjoying it but I was surprised that the steam trading cards tag (on the right of the store page) wasn't there. This seems to be the only way to let Steam know it's missing & that this game has Steam trading cards.

"In this exhilarating combination of terror and jigsaw puzzles," Can't say I've ever heard or read a sentence that put 'terror' and 'jigsaw puzzle' together. For that reason alone, I think I'll spend the $3.30 on this.
