EASILY worth $1. Could use one small tweak – Mate in 2 Puzzles Review

More clever, fun puzzles than I could ever solve! Once you get past the handful of "easy" problems, you get into the really clever, brilliant, fun puzzles – ones that might well take you an hour to solve. I think there are something like 1000 puzzles…? I am pretty sure there are more than I could ever do, and they're good ones too! There is one small feature that this app sorely needs: the ability to just freely move the chess pieces yourself. Part of why it is so hard to figure out how white can mate black in 2 moves is that you can't try a white move, and then try black's various responses for yourself. You can try a white move, and then the app will make black's move – presumably black's best possible move – but that's not the same effect, since it can lead to you accidentally "solving" a puzzle when you just meant to try out a theory. If they could fix that – maybe by offering a Sandbox button, where you can then move the pieces freely – this app would probably be worth $5. But still, 1000 clever chess puzzles for $1 easily deserves a 5-star rating! Additional note: I don't know why someone said the app won't give you the answers, because it will if you click the Hint button.
