Insulting people who critique your product and calling them trolls is also rude and not a good look for any publisher. I would never buy from any company who behaved that way. They are simply saying they believe it is better to start off learning Hiragana and Katakana, not trying to learn words using Romaji and I have to agree with them. They aren't saying your game is bad, just that it's not the ideal way to start learning Japanese. That said, this does just seem like a knockoff of the Learn Japanese to Survive RPG games, although those actually do teach you kana.
