Thanks for the feedback!
I’ll speak with the team about the potential for adding some interface options to customize the mouse pointer - both in terms of size and in terms of colour. This might not be something we find the time to work on until closer to the game’s release, so I’d be inclined to second @DYSFUNCTYNAL’s recommendation to try using YoloMouse.
I can also confirm that this isn’t - and assuming the functionality doesn’t change, never will be - considered a violation of the Terms of Use. We recognize that there are many legitimate reasons why someone would wish to customzie the mouse cursor, and we are content for players to do so either through in-game options provided in future, or external means of doing so.
