Introduce a colourblind feature
I think it would be super helpful to introduce a colourblind feature for the part of the player base that is colourblind. Ideally one that lets you adjust on a scale as not everyone with colourblindness has it to the same degree or even the same type. The colours become super muddy and it becomes extremely difficult and at times impossible to differentiate objects. Introducing this feature as optional in settings would allow the people who need it the opportunity to use it and get some more enjoyment out of the game, ultimately making it more welcoming and accessible.
