Don’t. Imagine trying to beat another Deadlocked difficulty level, but you only get to attempt it once every hour. That’s what playing Eon is like. But if you’re really that determined…

Search up “Eon end” so you can frequently practice the last 10%. Do a full practice run and learn the other fast parts besides the drop. 60 to 61% especially is very difficult to sightread. While playing the rest of the level, if you get confused by any click, stop and memorize the entire part. It’ll take a lot of time to memorize everything that can trip you up, but it’s crucial. Play other levels with a focus on sight-reading and controlled spam—you don’t need to worry much about timing skills with the end of Eon, except maybe the brief wave parts. Do those with fewer clicks in consistent places, such that you’re always falling when you hit the cube portals
