Iiii totally forgot about this project.
I guess most of my latest maps apply for this? Having a hard that rounds up to less than 4.5 stars and also an easy and a normal AND a cool insane or two~
Gonna suggest a few of my best.
http://osu.ppy.sh/s/14868 - MSI - Stupid MF (Many people said they loved especially the Easy on this, and it overall seems to be a very liked map. Has easy, normal, hard, insane, crazy)
http://osu.ppy.sh/s/16572 - Paramore - Where The Lines Overlap (Generally very liked map, and I'm personally also very happy with it. Easy, Normal, Hard, Insane)
http://osu.ppy.sh/b/72189 - Marina and the Diamonds - Oh No! (Hooray for guest normals. I'm extremely happy with how this map turned out, too! And the Easy has slider art! Easy, Normal, Hard, Insane/Crazy)
