Oh yeah that final floor thing was fun, you have to win 5 out of 6 games in a row to earn the privilege to stay up there, if you lose twice you get kicked down to floor 10 and you gotta get another winstreak there to get your chance to challenge the celestial floor and the people you fight during it are most likely all gonna be people who have been fighting eachother up there for a while so it's legit hard to get that golden VIP icon and not get kicked out of the lobby any longer. And then you become the gatekeeper kicking people out of heaven lol. Also points/levels are super inflated by winning up there, I was at like nearly lvl 300 (3 billion points) by the time the beta ended and getting all the way up to floor 10 was maybe a third of that, the rest was all just playing in the celestial floor lol.
What's unique about this is that it only gatekeeps good players normally, since if you qualify to floor 10 you can't join any lower floor and bully newbies, but newbies can choose to play in any floor they wish to if they feel up to it, but that's not actually true for the celestial floor since you need to get that winstreak to even see that the floor exists. So at first it feels like it punishes you for being good but if you get really good then it rewards THAT lol.
Also I'm surprised Max is talking about burst awareness as if it's something you hone by being a Strive dev, when bursts have been in the series for over 15 years, and learning to look at the burst gauge and bait bursts is a fundamental of GG. I guess he never knew bursts existed before or never got to the level of thinking ahead enough to include burst-safe combos in his repertoire or something? Either way though, that dev wasn't doing anything that is only doable by being a Strive dev in that video, you just need to have played GG for a bit and you can do the same.
