OD 9? Really? I think Makar was right about the OD on this map.
It would be fine if the song was very dense in objects, and for the most part it is, but there's a bit at the beginning that is off-putting at OD 9.
00:19:990 (1,1) - Namely these two objects. Because there isn't a clear beat before these objects, the player has to either keep an extremely fresh idea of the song in their head or do extremely well at reading approach circles. Compared to the rest of the map, those two circles are asking a lot.
