My Idea is to make new mod to osu play i mean " Hidden Cursor " ,where a cursor is invisible and are visible only at time breaks ,the rest of this idea is up to you osu team . Tahnks For REading And sorry for my bad english ;(
It was decided that a mod like this wouldn't really have much entertainment value and if you really want to try it out yourself try looking into skinning and creating a transparent cursor for you to use.
