In my 29:20 run on January 31, 2023, the Capacited Flux boss skipped over the death animation, and seemed to grant the boss an extra hit point before that happened.

I was just playing World of Dreams again, and discovered the same glitch between health points, effectively skipping over one left-right missile phase. If we can figure out what causes that glitch to occur, we can exploit it so that we may possibly only have to face the left-right missiles once.

I ran some tests to see what might cause it, but as it turns out, the number of bullets it takes to deduct one hit point is strange indeed. I fired bullets one at a time at it. Once, it took me 14 hits on the first phase, another time, it took me 22. It seems that the first phase is supposed to take ~20 hits, but I'm not sure if it's because the bullets sometimes count for 2 hits, or if the game changes the number of hits it takes. I'll keep this thread updated if I ever find anything new on this glitch.
