Thanks again for your advice, chryuop.
I tend to agree with you where Hiragana is a lot more accurate as compared to romaji, afterall it is the native written language. Because of that I am making a web game (which I will be posting on my site soon) for learning Hiragana and Katakana
I will let you know when that is ready to be tested, and you may help me to test it out too!
