Big-Lipped Alligator Moment: The level set in 15th century Italy starring Leonardo Da Vinci set to Freddy Mercury's "I Was Born to Love You". It's the only level that takes place at any time other than the present, and is the only level that doesn't have some representation during the final two songs. The only other reference made to it anywhere is a brief picture of its stars at the very end of the game.
The La La stage is about an anthropomorphic white blood cell fighting a war against a demonic-looking virus. That sounds a lot like Cells at Work!, don't you think?
Memetic Badass: Morris and Derek, namely because they can easily adjust whether they're dancing with J, Spin, or Chieftain. This has led to semi-serious theories that they are, in reality, the most experienced agents.
"You bet, kid!" Explanation Hulk's signature catchphrase, said no less than five times (four if you get the bad ending) over the course of "The Anthem". Naturally, players couldn't resist being drawn to it for being a Most Wonderful Sound.
A lot of the songs featured would normally be hated by the target audience, but their presence in the game redeems them immensely. "You're the Inspiration" in particular was a hugely hated and heavily criticized song back in 1984, before this game made it theTear Jerker anthem.
You could thank both the cover artists and the seamless integration with their corresponding scenarios for that. After all, who can argue with Jason Paige as the lead singer?
The song "La La" had a mostly lukewarm reception by music critics, who called it "insipid" and criticized its lyrics. The remix in the game earned a surprisingly positive reaction from fans.
This game contains the Hoobastank song "Without a Fight". And it is awesome in context.
Rooting for the Empire: Some of the people the Agents are supposed to be helping come off like they should really be the villains of the level, like an oil baron who spends all his money on his gold-digger wife, who you're supposed to turn into a Karma Houdini when his cries for help spring from his habits catching up with him. That's not even getting into "I Was Born to Love You", which straight-irons Leonardo da Vinci and seems to endorse stalking. Makes you want to throw the level just to see what "should" happen.
The Scrappy: Colonel Bob's gold-digging wife makes Norma and Isabella Carrington look like penniless saints in comparison. She clearly only loves him for his money, and unashamedly pissed away their fortune on herself. Never mind that she forces him out on the streets to work his ass off re-making their fortune back during the course of "Let's Dance" and, judging from the splash art you get for the best ending, with the way she's looking at the diamonds, doesn't appear to have learned a thing.
The spinners are not a very popular feature of the game. Would you believe they were worse in Ouendan?
Like with Ouendan, the scoring is highly combo-based; you get a multiplier proportional to your current combo. In other rhythm games, missing a note simply means you'll lose a few points; here, a combo break halfway through the song will damage your potential score to the point where you may as well restart.
Signature Scene: "You're The Inspiration", for the sheer Tear Jerker factor and being the one stage players absolutely refuse to fail on.
That One Attack: The final spinner on "The Anthem" in Sweatin' or Hard Rock difficulty appears so suddenly and gives you such a small window of time that you're prone to fail it. Fortunately, it's at the end of the song, meaning that if you've made it this far you're likely to pass the stage anyway, but it can serve as a kick in the nuts to those aiming for a full combo.
"Canned Heat" is tough on Cruisin' because its notes switch between vocals and the background's off-beat rhythm — you're used to tapping on the vocals, especially after "ABC" and "Material Girl". Sweatin' and Hard Rock! at least give you the benefit of enough markers to figure out what beat developers wanted you to be tapping, while Breezin' stays consistent from beginning to end by only making you tap on the vocals.
"ABC", on pretty much any difficulty. If you're going for all-300s on the higher difficulties, the sliders during the "A-B-C! Easy as 1-2-3!" part are pure murder, since to hit the beat right after it (which is across the screen), your reflexes tend toward jumping off the slider a millisecond before the slider actually ends, leading to a 100 (if not an outright combo break). Considering the (mostly) consistent beatspacing, the fact that that beat across the screen is pretty much the very next beat is frustrating for many.
"Survivor" can also be a pretty tough level for the exact same reasons.
"La La", on pretty much any difficulty. The challenge comes from keeping the health bar high due to the long pauses in-between sets of notes and the constantly-draining lifebar, which screws over any player who is trying to make a recovery and allows less mistakes than usual.
"You're the Inspiration" has several subtle differences from other levels, and, while it does keep the mood from being ruined, it also makes playing the song on higher difficulties far more stressful than it should be. First of all, there's no countdown at the start, giving the player little warning for when the circles start appearing. Second, unlike other levels where the circles' sounds are limited to drums and the occasional brass sting, here the circles can play actual musical notes and several drum sounds in a row, making it hard to discern which noises are coming from the background track and which ones are coming from the circles. While it isn't a big problem in Crusin' and Breezin' difficulties, playing it after the aforementioned "Canned Heat" and "ABC" levels on Sweatin' and Hard Rock is incredibly disorienting.
"Jumpin' Jack Flash" is an awesome song but it is extremely painful to play at times. Especially on the third section where it likes to throw lots of spinners at you in very rapid succession and then almost immediately switch back to tapping markers. Some could say that this level is a lesson in pure hatred and anger.
That One Sidequest: While not the hardest song to S-Rank, "Walkie Talkie Man" on Breezin' deserves mention for its Surprise Difficulty. Being the first song of the easiest difficulty, you would expect it to be a cakewalk; but in actually, everything the level does to make itself easier ends up making it harder. The slower tempo forces way more precise timings than usual in order to get 300s, and the low number of hit markers leads to a very low bar of errors (5 in total), tied with "I Was Born to Love You" on the same difficulty for the lowest in the game.
They Changed It, Now It Sucks!: This seems to be the opinion among several of the uh... more militant Japanophile fans of the original Ouendan, even though this game clearly retains all the Widget Series charm of its counterpart.
Woolseyism: To the point where it's a new game around the same gameplay concepts, just to make the humor and quirkiness hold appeal outside Japan. And for the record, it's become popular inside Japan as well.
