Crashes a lot

I like this app substantively, but, it would have been nice if there is an option to increase the size of the letters in tracing(PALAKA) option. For kids, the of the letters are very small. And also when you press forward arrow symbol number of times to go to a letter to resume tracing, it crashes. Something happens when we eraser number of times. If the developers can fix(I hope soon) technical difficulties of this app, then I would vote 4 stars for this app.
