A. the 'speed-up' is unnoticeable. (would be better if you make it complete the sentence in one go)
B. I've had it with three of the bosses so far
Dunno, the speedup is pretty noticable. In the code it is at least 2x as fast.
But yeah, some sort of skip, or simply a thing that prevents boss cutscenes from being played several times (at least if they are long scenes), is planned. Though I don't think it's quite as annoying as you make it out to be, but that might just be me.
