Read-Write Bengali Lite

I paid $1.99 for this only for my 4 year old daughter; otherwise I wouldn't have. When this program asks to trace the Bangla alphabets the third time without any help with dots, even I have difficulty matching it with the original and they say I have neat Bangla handwriting! Therefore, please make this program more flexible with regard to the third attempt for young children at least, because this program has potential.u I have also noticed that when I had initially downloaded this program, it was "lite" and even after making full payment on Apple Store, it still says "lite" on the program! Thereafter, I tried deleting the lite version by downloading and replacing it with the paid version since I've already paid and upgraded while using this lite version, but your paid version still asks for $1.99 from users who have already paid for the same on the lite version! I had no option but to redownload the lite version for which I've already paid. Also the quality of sound is low for children to follow; the sound needs to be crisp, clear, and loud for them to learn and follow. Hope I don't have to pay again for the next update; otherwise I will have no doubt in my mind that this program is a rip-off! Regardless, so far, this program holds potential if you (will) pay close attention and address my aforesaid comments, since (I have personally found that) the other Bangla learning programs on Apple Store are not even worthy of one star.
