About This Game

When a global war nearly decimated humankind, an evil military organization called Oniken takes advantage of the situation to dominate and oppress the few remaining survivors. Even though any resistance to this organization seemed hopeless, a small rebel movement organizes strikes against Oniken. One day, a ninja mercenary named Zaku offers his services to the resistance for unknown reasons. His moves are lethal and now he is the resistance's only hope.

Oniken is an action platform game highly inspired by the 1980's, its games and its movies. You can see this not only in the graphics and sound design, but also in Oniken's story and difficulty.

Don't Worry, You Will Die A Lot Of Times.

First impression: Not feeling the love so far. While the visual presentation is certainly nostalgic, the game just doesn't play well. The movements of both your PC and the enemies are twitchy. This, combined with the extremely limited movement set in relation to the level design, just makes the game artificially hard.

I love a good challenge, but Oniken doesn't give the player the tools needed to face its challenges, which makes it an exercise in frustration and repetition more than anything. Good for a bit of nostalgia, but it has nothing on the NES games it tries to emulate or other throwback games like Shovel Knight.

I will give it more time to see if it picks up, but for now I'm not impressed.

I think the game was inspired by games like ninja gaiden a bit too much , the levels are punishing with pretty much undodgeable attacks unless you got hit once and now know they're comming, the first boss fight is pretty dull, the only way to beat it is to save grenades, have a sword upgrade or damage boost. speaking of damage boosting, i was never really a fan of getting knocked back when i get hit, especially when the thing hitting me can't be attacked (rocks after the first boss, sure you can slice them... when they come to your sword level, but since you can't attack upwards it doesn't really help now does it.). especially when you're platforming over an instakill pit. oh and btw , no checkpoints, if you die at boss you gotta replay the whole stage again.

The only redeeming quality i can say it has is that i like it's artstyle. i might revisit the game in the future, but for now this is my oppinion

Pretty unforgiving, frustrating, satisfying.
Only 1 attack though and the SUper attack.
Enough variety to keep you entertained 'till the end.
Nice art, music.
Worth a buy.

The review blurbs don't lie: This game absolutely feels like it came right out of the late 80's NES but with fine tuned controls. Everything about it screams classic from the NES style color palette that neatly separates foreground from background and makes sure enemies stand out clearly to the hard as balls platforming and combat, to the sparse checkpoints and lives and unforgiving boss battles that can crush you in an instant if you don't learn their patterns.

Gameplay feels like a mix of Strider and Shatterhand with swords and grenades as your primary weapons. A power-up item lets you cast a crescent shaped beam half the length of the screen with your primary attack but fails after you've been hit twice, requiring you to not only master the new attack range to keep enemies at bay but also hone your platforming and dodging skills to maintain your elevated attack power for harder enemies later in the stage.

The Terminator meets Vexille meets any kind of robo apocalypse storyline is pure '80's cheese and it's glorious, especially when a dude called Rico calls you on what looks like an '80's portable TV while you're riding a bright green rocket powered jetski. There's even a villain that feels like a pure throwback to the infamous Cats from Zero Wing.

Despite all the homage to action games of the late '80's, Oniken manages to be its own beast. It doesn't feel especially unique but it doesn't have to as it's a masterfully crafted experience that's equal parts nostalgia trip and exciting. Even with the harsh difficulty I find myself wanting to see what the next screen will be, what the next villain will be, what's the next enemy the game will throw at me and what will it do.

The audio feels ripped right from the era too, a masterfully crafted score of synthetic sounding music that perfectly fits the tone and transports you back to a childhood full of bleeps and bloops and incredible ear-pleasure that you're sure your audio chip is having an ♥♥♥♥♥♥ to produce.

Controls are tight, responsive and the ability to use the dpad or analogue stick makes everything a bit easier (or more authentic depending on how you look at it). Restricting controls to two buttons (attack and jump, with grenade being up+attack) feels like an unnecessary nod to the NES but it's not restricting or annoying. Neither is the game in general - when you die it's almost always your own fault, you own mistake or lack of attention that causes you to fail. That said, enemies are fast and unpredictable (at least the first time you meet them) and you'll get caught off guard by a rushing machine or chucked grenade more than once.

So do I recommend the game? Absolutely. No other game even comes close to the level of authenticity that Oniken achieves and it's obviously a labour of love from the developers who are very talented. The game isn't perfect though, for all the praise I have to give it the flashing backgrounds in some cutscenes are an epileptics worst nightmare that can't be disabled (except by skipping the whole cutscene).

Score: 9/10 robots stabbed in the faceplate.

There are TWO games on Steam that play and feel like classic NES / SNES games.
Oniken is one of them.

Many side-scrollers and platformers claim to play and / or feel like they're out of the 80's. Like they are from the (S)NES era.
They all lie!
Some of them really do look like NES games. Some of them look like HD NES games. Some of them claim to play like NES games while looking totally "new-age?". None of them really plays nor feels like old-school retro side-scrollers tho.
I'm not saying they're bad games. They mostly aren't. But they don't feel nor play like (S)NES games.

Oniken, however, plays and feels exactly like a classic NES game!

I was sure that Oniken is another one of those pixelated games that is super hard, claims to be "old-school" but doesn't feel or play like an NES classic and once again poor old Mets would be dissapointed.
I still gave it a shot and WOW! Just WOW!
Oniken feels just like it came out from the 80's!

Unlike any other false "old-school" games on Steam, Oniken keeps it simple: You have 2 different attacks (one of them being a pick-up), you can jump...and move back and forth. The game is hard tho. Not Ninja Gaiden hard, but hard. Challenging is the key word here.

Easy to get into, hard to master.

The combat is smooth - Your main weapon is a sword (that looks like a katana) and you can throw grenades as a secondary weapon. Grenades are pick-ups tho and you can run out of them. You can also find secret 1-UPs and some sword power-ups if you get lucky.

After each level you get rewarded with a cutscene that has the quality of Ninja Gaiden.

I managed to finish the entire game in 6h...it's possible to speedrun through the game in 15-30 minutes tho. Just like with classic NES games. Their true lengths were about 15-40 minutes but they took hundreds, if not thousands, of tries to finish.
There are 6 stages and each stage takes you about 2-5 minutes...That is if you know what to expect and you're familiar with the level layout. The first playthrough will take some time. I especially hate level 4 which took me the longest amount of time to beat.

10/10 - Nails every aspect of being a good NES game!

If you're looking for a throwback then this is it. Look no further! Buy Oniken!

Sometimes you just want to slash people in half and use no more than a couple buttons to do it. Reminiscent of games like Strider, Ninja Gaiden, and Shatterhand, Oniken is a brutal and brutally difficult 8-bit platformer that isn’t for the meek. Games of its style have been common as of late, but none feel as authentic as Oniken. For better and worse, one could easily mistake Oniken for a lost Nintendo game by Nastume or Tecmo.

Call it indie if you like, but teams of two to three people were commonplace during Nintendo game development. Some did great things within the action-platformer genre, of which Oniken belongs. What we now see as limitations of hardware, they saw as a framework to build within. With 56 colors, a goofy-sounding synth, and four buttons, a few talented designers made games that continue to entertain us many years later. Oniken aspires to be in their company, even if it’s from a different era and on a different platform.

As an outsider, simplicity and difficulty appear to be the two main design philosophies of Oniken. We’ll talk about the former, before my blood starts boiling at the thought of the game’s bosses. Designed with a gamepad in mind, Oniken centers around one mercenary ninja’s ability to jump and slash dystopian future jerks. Zuku, the game’s protagonist, isn’t as fluid and fun to control as Strider Hiryu, but his sword has a nice reach. You can extend that reach by collecting power-ups. However, you can easily lose these upgrades by taking damage. If it isn’t clear by now, Oniken loves to punish the player for making dumb mistakes.

Luckily, Zuku has a couple of extra tricks up his sleeve. In addition to extending attack reach, Zuku can sacrifice his power-up in order to go into berserk mode, where he deals more damage and takes less. Just as the power-ups render deadly enemies harmless, berserk mode can turn some of the game’s most difficult bosses into a 15-second slashfest. Only the most masochist old-school players will complain about these cheap victories, because even when you do manage to berserk a boss, you likely have died from him many times before - if not during the long trek to his room.

And finally, there are grenades. These are used much like items in Castlevania: awkwardly hold up and press attack to throw in an arch. Unlike Castlevania, this is the only item you'll have which is pretty disappointing. You get used to jumping and throwing grenades, but it never feels quite right. This is one of many instances of how Oniken’s earnestness to emulate Nintendo games disservices the overall experience.

Oniken packs a lot of variety and creativity in its six levels which contain three areas each. Sometimes you’ll be platforming across conveyor belts with lava beneath while other times you’ll be force feeding grenades to a cybernetic polar bear while jumping spikes on a speeder bike. One area you will find consistency in, however, are Oniken’s tough-as-nails boss fights that demand you to quickly recognize an enemy pattern and stay the hell away from projectiles.

Most of the time, these boss encounters are a fun challenge, but a couple will frustrate in a way that is neither fair nor entertaining. One such boss is a snake that breathes fire down on you if you attack it. Not taking damage is a matter of endurance and luck. This boss is followed by an even more maddening boss: A robot you must fight from a small, moving platform - fall off and it's instant death. Until you recognize the specific attack pattern and necessary approach that a boss demands, Oniken will put you in a world of hurt. Once you run out of lives, you'll have to start the ~15-minute journey to the boss again.

While Oniken’s difficulty is decidedly old school, there are many times where I think the developer could have reconsidered its approach. Castlevania and Ninja Gaiden may have contained instant death traps, pits, and cheap aerial enemies, but these were not the things that made those games good. In fact, these are the things that keep many players from returning to them.

One aspect of tribute that can’t be knocked is the game’s presentation. 8-bit indie games are a dime a dozen these days, but rarely do they sound and look as great as Oniken. Though the backdrops and animation lack some detail displayed in the best Nintendo games, it’s an impressive effort nonetheless.

Oniken isn’t quite the magical pairing of nostalgia and great game design that Mega Man 9 was, but it comes close to scratching that same itch that few other games have done since. If you love 8-bit games and hate yourself, dying repeatedly within Oniken’s six merciless levels brings its own form of joy that is rare in games these days.

Oniken is a 2D run and sword action game. The controls are simple, attack, jump, duck, berserk and up + attack to throw a grenade. It is all so nice. The attack distance is good and can be boosted with power ups you find. You can hang from things. This game really goes the extra mile to make you think you're playing something for the original Nintendo, while most other games going for the nostalgia feel don't have actual 8 bit graphics and music. I feel such a buzz playing this game unlike other 'retro-ish' games that miss the mark with modernized graphics and sound.

The cut scenes are nice to look at, but the real fun of the game is the game play and the enemy variety. You'll see a lot of enemies and tackle them in different ways. For modern gamers the game might be seen as difficult due to the fact if you die, you restart the section of the level. Die at a boss, restart that entire section. You'll get better! Lose all of your lives and you'll have to restart the level. Each level mainly consists of 3 sections, each with a mini boss of some sort. Since the save file allows you to just jump to a level, if I die on the first section of a level, I just go back to the menu and warp to the level I was on. Kinda makes lives on the first section of each level pointless. You have a hefty health bar like Mega Man, so the game is pretty forgiving. Pits are of course instant death.

The level variety is a mixed bag. Some levels are just bluntly walk to the right, others make you scale to the top and still others put you in a jet ski with a scrolling screen. There are a few sections that feel open where you're free to make your own path, which feels good. Some levels are needlessly difficult with a lot of action happening, but if your a veteran of old Nintendo games, you should be used to it. If not, then make an angry video about it.

There isn't that much replayability for the game, there are a few hidden items, one per level, and there are achievements for beating a level without dying. The game saves your high score for each level, but really, once you've beaten the game, there's no reason to come back to it.

Again, this is an awesome game well worth $10, it is so awesome that I'd buy any other game this studio comes out with. They hit the nail on the head. If you aren't into old school Nintendo games, avoid it.

What can I say? An indie game done in a retro style with colourful graphics, precise controls, and awesome gameplay. The game only has six lengthy missions, but a game over means restarting the mission from the start. It's very easy to recommend to fans of retro games.

Hard as balls like some older NES games. Not as hard as Ninja Gaiden, but I knew I wouldn't be able to beat it unless I dedicated several hours to it. That being said, the game never made me angry even once. Any time I died felt fair. It's a very easy recommendation from me!

I didn't have much patience for this game the first time I played it.
Like many others I treated it as some crappy $1 indie game with pixel graphics that I bought on sale.
Coming back to it though, I can see why others liked it and am actually starting to enjoy It myself.

I didn't play the types of NES and SNES games that this game tries to emulate as I was far too young and only enjoyed first party nintendo games.
I have been playing a lot of NES/SNES inspired games on steam in my adult years though and I can definitely see the influence in the game from games like strider and anime such as fist of the north star and possibly berserk.

It is clear to me from seeing this game and their other game which is a faithful homage to castlevania that these people thoroughly revere and love the classic nintendo games.
Others may complain of unfair difficulty and cheap hits (staples of early arcade and console games) and I'll admit those annoyed me at first too.

And then I came back and finally started beating levels and It occurred to me what type of game I was playing. The levels are short, and you have checkpoints and extra lives at your disposal.
The game expects that you will die and next time through remember enemy placements and effective attack patterns. You were never meant to breeze through this game in one try.

Controls are simple, enemy attacks can be dodged if you learn placements and timing and you're given a fairly large health pool and plentiful resource drops (considering what type of game this is).
Much as I hate that everything gets compared to dark souls, It's the same concept here: be patient, look out for patterns, expect to die a few times until you learn and git gud.
