suggestions

During battles the opponents attacks are coloured grey and on a black background they can be hard to see. I think it would be a good idea to have an option (much like the option to change the colour of your bots name) to choose different colours for your attacks.

So when they hit you could have the damage number in red, and when you hit them you can have your damage number in green or blue etc

I kind of like this idea, no real downside to it, just not top priority right now i would say.

This sounds like a good idea +1

A further suggestion based on this - if an attack takes 10% or less damage the colour can be green (example) 10.1 - 20% - Amber and 20.1% + red.

You get my point anyway, % and colour could vary this was just an example
