There's 3 things that make it faster than what you remember it from BN:
- it's geared towards BN upgraded bosses/superbosses/post game content, not regular BN. Watch a V3 or Bass fight (or just anything on BN3 post game scenario, really) and you'll see what I mean
- there's no turns
- there's no invincibility when you or the enemy gets hit, which gave you an instant to think/reposition for free. Here everything is taking damage all the time
But yeah, the readability of the screen sucks, for a lot of reasons, from lack of animation feedback, lack of contrast, bad information architecture on the UI, bad UI decisions in general (you can see the money visual effect coming to your character, but you can't see how much money you have or won until the battle is over, which makes pretty hard to know how much money you get from a regular fight vs saving a money hostage and how much bonus you get from flawless victories, to name a single functional problem).
Super agreed on the soundtrack!
This video explains the overall game flow and basic mechanics, and I made a
bullet point write up on stats and keywords with a couple of examples last page (repeating some stuff from the video). If there's anything else you need help with, just ask!
