Fun and easy

I have tried other slide puzzles before and they don't slide as easy. I enjoy trying my beat my own time. What might make this even better is if they pieces had a picture and not just numbers.

15-puzzle review

You have RUINED this game! It is no longer enjoyable to play. I cannot even effectively slide the tiles the way I have for the past 60 years (Yes, I started playing it way before the electronic version.)
The only question I have is, “WHY have you chosen to ruin a previously-enjoyable game? Please, please, answer my question.
PS The only reason that I rated your new version 1-star out of 5 is because I didn’t know how to rate it zero-stars! In other words, I think the new version is worth zero-stars; while the old version— the version you presumably willfully ruined — was worth 5-stars!

A few months ago I mentioned that a way to check how many times you've completed the puzzle would be great for frequent users of the app. I really would appreciate if this was added in an update. Then I would give it the full 5 stars. Until then, that is my only concern for the app. Please add this feature! I know this stat is kept somewhere, otherwise the achievement for completing 500 wouldn't be possible
