The concept really appealed to me. Playing the demo confirmed it. Have to echo another comment that said the way you write children is very realistic - they're not acting like literal toddlers, but they're not mini-preteens or mini-adults, either.
I also have to say that I very much appreciate the option to change pronouns at every step of the game. In fact, the roleplaying that's already in the demo is a fair step better than some other games I've played.
I have to ask out of curiosity, is facial hair a possible customization option for adult Cove (or adult MC)?
