Undo should undo moves
(from Kalani by email)
Consider letting the "undo" option also subtract a move from your total. Logically, if he wants to undo some move Xn after moves X0,X1,X2,...Xn he can restart the game and then repeat X0,...X(n-1) but that's tedious and it makes him want to put the game away.
DragonBox 1.1.1 solves this issue. It’s released everywhere except on Mac where it awaits review and should appear during the week.
We've fixed this issue for the forthcoming 1.1 release. Now Undo will undo moves!
