Hi,
I uploaded a new, refined version :-)
Main improvements:
- More intuitive animations, that clarify the relationship between cleared areas and rotation credits bar on top.
- 2->3 undoes and 10 moves back instead of 5 - less risk to loose your highscore when you're stuck. Also, more generous Rotation Credit bonuses on achieving the daily goals.
- Sharable highscore
Many thanks again, for all your feedback!
If you have any additional suggestions, they are always welcomed :-)
