The game itself is fine. But sorry to say that - the gender selection killed it for me. Game industry makes big efforts to create female role models that are differentiated and complex - as counter model how female characters were represented in earlier days in gaming industry. Also the LGBT community plays a role in gaming economy and getting more attention by growing events that support LGBT - or were organized by LGBT. Better keep this in mind.
Nowadays you should avoid making those mistakes. Making a gender differentiation based on "female is pink" is part of an oldschool sexism and is highly disrespectful. Bringing a gender differentiation in a game that does not need it (a red dragon is pretty neutral) shows that this act was intended. So it comes along like a very bad joke.
Better make a simple color selection instead (like "Having a choice of 6 uncommented colors"). You hurt no one by doing that and this can highlight your game (comparing it to Yoshis Island where you play Yoshi in 8 different colors).
