While going through Warioware: Touched! last year, I had my fair share of criticisms, mainly that the game felt somewhat trivial since every microgame was some form of poke + drag (or in the case of the mic games, just yelling til I won). On a surface level, it would appear that the other major Nintendo minigame collection series, Rhythm Heaven, falls into the same trap, since every game appears to be tap and flick, but I don't find that to be true. Quite the opposite in fact, as Rhythm Heaven DS is extremely challenging, yet super satisfying and fair.

Rhythm Heaven succeeds where I think Warioware: Touched! falls flat, because the former is much more subtle about mixing up devices to introduce an organic difficulty curve than the latter. Every minigame's gimmick is conveyed via some combination of call & response, memorizing rhythmic motifs, and recognizing appropriate audio & visual cues. This difficulty then gets ramped up, both within minigames and throughout the game's progression, by introducing new or different elements that alter how the mechanics are presented and utilized in some fashion, but ultimately retaining the core fundamentals. For instance, you might have to play "in the dark" for certain sections of minigames and rely heavily upon audio cues, or have to deal with sudden (yet firmly telegraphed) tempo shifts with tougher rhythmic variations, or even shift the backing melody or player actions to the off-beat to keep the player honest and in-tune with the minigame's workings. This, combined with the simple yet realized controls of tap, hold, and flick (lending itself naturally to syncopation from tap/hold + flick alongside quick note playing from tapping) allows for a much more robust toolkit and strengthened intricate designs for a broadly diversified minigame ecosystem. Even if all these different rhythm games revolve around the same theme (i.e. finding the natural flow and beat in simple and often mundane tasks), they all manage to stand out from one another despite seemingly simple controls because the rhythms at which they are executed from one another can be so drastically varied and iterated upon.

The attention to detail is especially evident within the remix microgames at the end of each five game minigame chain. These finales add a fresh coat of paint to the previous four microgames (and once you get past the initial 30, sometimes even more than just four) and putting players' execution and knowledge banks to the test while ferrying them between the different concepts with ease. There's an overlying melody to the whole affair, just played with a different filter for each specific minigame type, and moreover, they're linked in a way where the players can recognize the carried-over beat and be in specific positions where they're ready to quickly adapt to the new control scheme. For instance, consider Remix 8: the ping-pong into vegetable slice looks intimidating at first, but once you realize that swiping the paddle in the former has the exact same rhythm as swiping to slice vegetables in the latter, then it's merely a case of recognizing the visual/audio disguise and maintaining your composure. Another example that comes to mind is within Remix 10, where there's a section transitioning from the snowboarding minigame to the choir kids' Glee Club. Normally, you'd think that there would be some issues immediately flashing into Glee Club, since you can't possibly know what's coming up without prior experience and not holding your stylus on the screen will result in your Choir Kid automatically singing as per the control scheme of hold and release to play notes. However, this is accounted for with the lead-in snowboard minigame, because the last few frames of that section telegraph a jump, which requires the player to hold down the stylus on the screen and then flick and release. Since the jump hasn't occurred yet, the player should still be holding down, and this transitions naturally into the Glee Club's neutral state, where they can then release the stylus to the telegraphed beat and proceed onwards. It's little moments like these that make all the different jumps between previous minigames feel seamless, and transform the remixes into challenging, yet extremely fulfilling victory laps.

My only outstanding complaint is that certain minigames require considerably more accuracy and precision to master than others, and are often far more finicky about their timing requirements without obvious visual/audible feedback regarding slight misses, which can make repeated plays for that Superb/Perfect ranking a bit obnoxious. Glee Club and Moai Doo-Wop 2 are two of the more infamous culprits, to where some users have even created strategy guides. I can certainly relate, as it took me over 8 tries on Glee Club to snag a superb before I realized that the tight timing during the quick notes in the middle of the track was the section that was stumping me, since being off by just a hair there doesn't result in the other Choir Kids giving you the stink-eye. As a related aside, I did have a bit of difficulty with Rockers 2, since this minigame introduces the use of the L/R button as a whammy bar and feels a bit out of place, being the only minigame that doesn't exclusively use the touchscreen and forcing me to bend my left hand around to access the button. That said, I'll choose to chalk that one up to a skill issue since the unlockable Technical Guitar Course afterwards gives you plenty more opportunities to get used to this mechanic. Regardless, I find Rhythm Heaven to be a very honest and approachable set of minigames despite the level of mastery often required, and I can easily see myself coming back to this one to spend more time honing my skills. It's a complete and realized package that's truly the epitome of doing a lot with very little, and I eagerly look forward to testing my mettle with the remaining games in the series.
