I got 20k Rhythmia and beat Chaos up.
Anyone else, who has played the first one, noticed that this game is much easier in terms of getting at least an S rank in all songs?
Chaos is the 20k Rythmia boss, Feral Chaos is a beefed up version that rarely appears in a Quest.
But yea, the system is more lenient, but as others have stated; there are more tiers to achieve.
Here's the breakdown
SSS 9750000-9999999
SS 9000000-9749999
S 7000000-8999999
A 6000000-6999999
B 5000000-5999999
C 4000000-4999999
D 3000000-3999999
E 2000000-2999999
F 0000000-2000000
