Great I love the ability to change the color, I use a blue stone color for the background and black for the digit. Easy to see and appealing to my son. I just wish the digit size wouldn't go so big that it stretches off screen.
This is a great idea!!! My kid lives it, plus the english accent is great.
Improved animation (slide and fade) upon slide or tap. (raising CF - coolness factor :-) )
Some bugs were fixed.
Improved internal logic & performance.
Added mechanism to collect errors as they occur.
Lots of love :-)
