Tap Away-3D Puzzle Hack 1.1 + Redeem Codes

At level 29, and starting with Level 25, can no longer rotate object on iPad, is this deliberate?

Also, having to play several different attempts on each level to receive a solution that is actually solvable, is this accurate? Or are all attempts that are generated actually solvable? After playing Level 29 several times, I am of opinion that not each attempt that is generated by the game is actually solvable, which is why I am inquiring. Too many cubes are generated in down position and the object cannot be rotated anymore to remove these cubes, which blocks a solution.

The game is ok, but I got to a level that is not possible unless you change the colors, but no instructions.
