a pleasant experience!
Surprisingly tight to speedrun (especially after the update making it harder to damage boost).
I got ~1:50 before the update (timing by myself) and have managed to just to get a 2:08.59 [9 hits]-- it's very suboptimal though. The crux of the difficulty (now) comes from being able to do all the damage boosts well (without accidentally damage boosting any earlier).
1:5x should still be doable with any clean run
