Hey,
Yes, this is something I am currently looking into implementing into the game when I can. I've not created/coded anything like this before, so I'm still in a learning process with some stuff. Once I got the knowledge on how to do this, it will be available.
Currently there is about 8 different font choices you can pick from. I'm aware this doesn't help with colour, and I apologise for that part. Although, there is a text to speech function within the game at the moment.
