Keres

Keres is an upcoming Extreme Demon mega-collaboration hosted ItsHybrid and set to be verified by ViewSonic. It is a buffed/extended remake of Erebus, a level that was famously put in the RGB trilogy. Despite the pre-extension restoring most of Erebus' somewhat simpler gameplay, the extension contains considerably rapid duals along with very complex gameplay. The level is set to be in the top 10 area on the Official Geometry Dash Demonlist, and ViewSonic currently has a run of 40-100%.
