It should be obvious (and already stated everywhere this discussion has ever taken place) but with the assumption you have been living under a shell and aren't being ignorant, and for verbosity I will provide an answer./me love ppy
osu! is a game about community and creativity, so the idea is that you are playing the map as it was intended by the creator at least once. If you don't agree with how they shaped their map, you can either:
a) Delete it before passing it as they intended.
b) Accept with how they made it and enjoy it how it is.
c) Stick with it, pass once and then have it your own way.
If you disagree with how I have implemented this, then I suggest you just quit this game. Because I am not changing how this works any further.
*semi-transparent circles + all map elements = love, seriously, I love it this way ;_;
