Fantastic!
Beautifully implemented interface, nice and clear icons placed right in the center on level completion, good background music.
I particularly liked the design of some of the last puzzles: To meaninfully cut down on possibilities, I needed to switch strategy from 'which piece will fit in this tricky bit of the board' to 'which piece will fit in this tricky bit of this other piece'.
Very well done, Jeddahbikers. Thanks.
One or two suggestions for a sequel: a little transparency in a piece while it is being moved would be nice, as would more levels!
