Continuing from the first game, the brand new Splatoon 2 again comes with the rhythm-action minigame of Squid Beatz 2 (イカラジオ2, Ika Radio 2).
In case you don't know, you can unlock the original Squid Beatz via completing additional amiibo challanges in Splatoon 1. Though being mostly just a music player, you can call upon the rhythm-game part to have notes flow from right to left along a line.
The original was more of just "something to do in this music player", but the new installment has powered-up the gaming aspects including actual hit judgement and scoring, plus gold and silver squid trophies for completing each notechart.
In short, the pink notes (sounds like dons) have you press the direction or A/B/X/Y buttons, the green notes (sounds like kats) takes the shoulder L/R buttons, and the bordered notes needs to be hit on both sides. What is different from Taiko no Tatsujin, in addition to the pink and green notes split into two rows instead of one, there are also places that you have to press pink and green notes at the same time.
The actual difficulty level though is familiar if you play Taiko no Tatsujin well enough. Most HARD notecharts tops at or under Oni ★9 with your typical 16th and 24th clusters and streams.
...wait hold on, that phrase sounds so similar back there...
Huh, so for eight whole stanzas (notes 316-398 and then 405-415) of this Koikuchi Shiokara-bushi (Spicy Calamari Inkantation) HARD notechart above is exactly the same as the current Taiko no Tatsujin notechart for Calamari Inkantation Oni (notes 249-331 and 342-352) on the Yellow ver. arcades. Good time to remind everyone that the Taiko no Tatsujin Switch is still in the works?
