Sometimes all you want is for a game to be mean to you again.
One of the very best things about classic gaming, at least from the perspective of the average busy adult, is just how concise these old titles can be. In most cases, game makers of the past had no other choice. From the primordial dawn of the hobby on 1960s university mainframes all the way up to the widespread adoption of CD-ROM technology roughly three decades later, every byte of precious memory counted. Skilled programmers were still able to realize RPGs and other intricate games featuring dozens or even hundreds of hours of play time, but this often meant embracing a more modest audiovisual presentation to save space. For fans of these more cerebral offerings, the tradeoff was well worth it. Action gamers, on the other hand, had an insatiable fondness for spectacle that often placed the developers of their favorite releases in an unenviable position. How could they consistently dazzle their audiences with the most detailed backgrounds, the biggest characters, the smoothest animations, and the most adrenaline-pumping tunes, all while still leaving room for, well, a game?
The enduring legacy of all these thorny compromises is a pantheon of tight, polished 8 and 16-bit thrill rides that experienced players can blaze through in well under an hour. Contra, Ninja Gaiden, Gradius, Mega Man, and many, many more, including my personal favorite, Castlevania. It’s only after you’ve played through one of these masterpieces countless times that their brevity begins to work against them. As pleasant as it invariably is to kick back and whip my way through Simon Belmont’s iconic debut vampire hunt, I’ve long ago reached the point where the challenge, even on hard mode, is deader than Count Dracula himself. Who can you turn to when your favorite hardcore action game just isn’t beating you down like it used to? The ROM hacking community, of course!
Hacks dedicated to furnishing veteran players with ferociously difficult new takes on old favorites are a dime a dozen and the first Castlevania specifically is one of the most frequently remixed NES titles. So why am I focusing on Overflow Darkness? Because this 2011 effort by Luto Akino is more than just your typical “Castlevania on steroids” with some extra pits and enemies sprinkled in. It’s tricked out with gorgeous new artwork, level design as well thought-out as it is brutal, and some clever tweaks to core gameplay mechanics.
Unlike Castlevania: Chorus of Mysteries, which I reviewed last October, Overflow Darkness doesn’t attempt to add any new characters or lore to the series. The scenario here is exactly the same as in the base game: Dracula is terrorizing the countryside and a whip-wielding warrior named Simon Belmont is out to destroy him. The only change is to Simon’s appearance. Instead of his original brunette locks, he’s sporting the long red hair from his 2001 Castlevania Chronicles redesign. While I’ve never been a fan of ginger Simon and was pleased when he reverted to a more traditional look for his most recent showing in Super Smash Bros. Ultimate, I actually don’t mind it here. Chalk that one up to the relatively simplicity of NES sprites, I suppose.
Speaking of sprites, it’s not just Simon that’s been re-drawn. Several of his familiar enemies have also been given professional quality makeovers, including Medusa, Death, and Dracula. Surprisingly, these new sprites are improvements in virtually every instance. Dracula’s demonic second form in particular is exponentially more menacing here than the bright blue “cookie monster” that confronts you at the end of vanilla ‘Vania. The new background tiles are just as impressive. The rather basic underground waterway at the start of level four, for example, has been re-imagined to great effect as a flooded catacomb packed with skeletal remains. None of the new art in Overflow Darkness stands out as the work of an amateur, which is just about the highest compliment ROM hack visuals can receive. Don’t expect anything so brilliant on the audio front, however. The track order has been swapped around, but it’s still the same Kinuyo Yamashita score we all know and love.
Pretty as Overflow Darkness is, it still wants you dead. Badly. The new stages here are all markedly more difficult than anything in the regular game, deluging the player with a near-constant stream of flying bats and medusa heads while placing durable enemies like bone pillars and axe knights in close proximity to death pits. It’s common to face off against several enemy types simultaneously on very precarious footing and some stages even open with Simon already under attack from multiple angles. Think fast!
Bosses have also been given a shot in the arm. The fight against the familiar giant bat at the end of stage one now takes place on uneven terrain with a hoard of smaller bats fluttering onto the screen from both sides. I lost several lives to this encounter, which is humbling to say the least. There are a couple of all-new bosses, too, and they have a habit of lurking at the top of the screen and showering Simon with projectiles, limiting the usefulness of the overpowered holy water sub-weapon in these battles.
Ruthless as these stages are, Overflow Darkness does play fair. Unlike T. Takemoto’s infamous Kaizo Mario World trilogy, the challenge isn’t predicated on tricking or teasing the player with deliberately absurd trial-and-error setups. It’s fundamentally the same precise combat and platforming as the “real” Castlevania, just with far less allowance for sloppy play. There’s considerable inventiveness packed into some of these new level layouts, too. The second stage contains a multi-tier “stair maze” that forces Simon to travel and up and down repeatedly across the same few screens in search of the door to the next section. Areas like this will push your reflexes and pattern recognition skills to their limits, especially since Simon loses a full quarter of his maximum health with every hit sustained from the very beginning of the game.
Yet another, more subtle layer of added difficulty is derived from the way item drops have been adjusted to be stingier than usual across the board. Remember how easy it was to score whip power-ups in the regular game? If you died and restarted with the weakest leather version of the whip, you always seemed to find a replacement upgrade an instant later from the very first candle you stumbled across. Well, forget about all that! According to Overflow Darkness, whip upgrades from candles are for the weak. Instead, you can only really count on obtaining them from random enemy drops and these can prove maddeningly elusive if luck isn’t on your side. The bottom line is that you’re going to become very adept with that puny starting whip, whether you like it or not. Sub-weapons and shot multipliers for them are also more scarce. Oh, and remember the large hearts that would increase your ammo count by five when collected? Overflow Darkness reduces this to two. The idea here seems to be to force players to rely more on deep mastery of Simon’s innate capabilities and less on exploiting power-ups. Although it can come off a bit heavy-handed and I certainly wouldn’t want to play this way all the time, it is a bracing change of pace from the default “melt everything’s face off with triple holy water” strategy most Castlevania players fall back on.
The takeaway here should be that Overflow Darkness is simply the best at what it does. Its stylish graphics, quality level design, and eye for fairness make it the current gold standard in extreme difficulty hacks of Castlevania 1986. There are other hacks available (Chorus of Mysteries, The Holy Relics) that are much more creatively ambitious, aiming to re-work the source material into something approximating a whole new entry in the series. These are well worth your time, but if all you’re really craving is a viable “super hard mode” for one of your favorite NES games, Castlevania: Overflow Darkness is the real deal. It’ll whip your ass and make you like it.
