Oh man you are absolutely talented with this one! I never even though about a full completion of TP Ceroba! Although I must admit, there were a few things that I do pretty differently compared to what you did for some of the attacks in Phase 1 For the exploding bombs attack. What I instead do is stand still on the bottom right corner. I find that some of the bombs that explode on the far left side have their explosions disappear before they could touch Clover! You usually get hit at most four times during the attack. But with decent chances of evading a hit I am unsure if you got confused on the pillar attack. But regardless, I just find that staying down minimizes the amount of hits you can take. At most, twice For the double sword attack. I go to the bottom of the screen and move in a circle while holding X to restrain my movements as much as possible. When the flower attack shows up, I hold Up to avoid it altogether. It usually results in a single yet guaranteed hit For the circling balls attack. I just go to the top-right of the border and stand still. Which is usually a no-hit unless one of the circling balls happen to hit you when they try to collide My personal best is a fight which used up 4 healing items (including one healing item consumed on accident) with the Delta Rune Patch equipped!
It’s the Speedrun Practice Mod for the game that can be found on the speedrun.com page. The speedrunning discord also has a good outline of the functions with hotkeys and such!
