“Kiai: Resonance gets right, aha, to the point. It’s a samurai duelling game about one hit kills. One hit kills were the speciality of the samurai in the Kagoshima region, where I studied.”

“This is not just a fighter, but a mind game that could bring a lot of tension to a genre that used to be occupied by feverish button-mashing.”

About This Game

Kiai Resonance is a 2D versus fighting game for Windows.

You take part in multiplayer samurai combats where one hit off-guard is fatal, and several challenges to perfect your skills. The player can change his katana position at any time to adjust to his opponent's, creating a mind game where you have to anticipate his next attack.

The graphics are attempting to restore the simple aesthetics of traditional Japanese prints by taking some pictorial elements of its great masters, while imbuing it with violence that characterized the confrontations.

Among the available game modes are included the classic one vs. one, either alone against the AI, two on the same screen, or online, as well as various mini games to test our samurai skills.

The game supports current gamepads, and online play with ranking system.

The good:

I think my favorite aspect of this game is how it looks like you're playing an animated painting. The art and animations are simplistic but really supplement the game. The gameplay itself plays out much like one might expect a one strike kill game to play. It's mostly a reimagining of rock paper scissors but with a twist. That twist being that you can see what your opponant is going to throw and can make changes, and so can he. So the match becomes a mind game as well as a test of twitch reflexes.

The bad:

Well the biggest problem that I've noticed is the lack of content and variation. All opponants look exactly the same and for all I know use the same AI. There's no kind of storymode that one might traditionally find in a fighting game. I haven't tried local versus mode, so I'll assume that functions, however the online competition has been a ghost town every time I've made the attempt.

Final thoughts:

Kiai Resonance feels like a great alpha build game. The core gameplay is beautiful and working as one might expect, but where's the content? Where are the different modes to offer some variety? I would be hopeful if this was an early access game that we might see the polish that this game deserves, but I see no indication that developement will continue. As of the time the I'm writing this review, Kiai Resonance is on sale for $4.49 and may be worth it just to enjoy the traditional styled Japanese art and get a small taste of some fun gameplay. For me, the lack of being able to do anything other than face the same AI over and over really takes away from the experience, so I don't see people really getting much playtime out of a title like this.

Kiai Resonance is a 2D samurai fighting game developed by Absorb Reality. In Kiai Resonance you play as a samurai and take part in quick fights and difficult challenges requiring fast reflexes as one hit kills in Kiai. Kiai Resonance is made up of singleplayer fights, multiplayer fights and challenges but my review is focusing on challenges and singleplayer only.

+Cool painting-esque art style
+Simple combat that's relatively easy to get to grips with
+One hit kill combat makes the fights interesting and short
+Three different combat stances to utilise, each with giving you a different advantage
+Interesting challenges
+There's a rush mode which makes you and your opponent charge towards each other at the start of the fight, makes things a little more interesting
+Good tutorial
+Full gamepad support
+Great soundtrack and soundeffects

-Kiai Resonance has a serious lack of content. There are only two characters to choose from. There are only three maps (four if you complete all of the challenges). There's no kind of upgrades or unlocks which doesn't exactly help its replay value.
-The multiplayer is completely dead
-Serious lack of graphical and audio options, all you get is Fullscreen: On/Off, Sounds: On/Off and Music: On/Off
-The singleplayer AI doesn't provide much of a challenge once you've got your head around the controls


Kiai Resonance is a good samurai fighting game with a nice art style and simple combat that currently suffers from a serious lack of content.

Red as autumn leaves...

...Will they accept me?

GAMEPLAY: The gameplay of Kiai Resonance is, difficult to describe. It is a two-player, two-dimensional (2D) duelling game. Basically, you have two players in a 2D plane fighting with the same weapon, to the death. Speaking of Death, it's a one-hit kill system. If the sword as much grazes you, you instantly die, making the game very tense. It also makes it, in a sense, strategic.

In my experience, most matches last less than a minute if they even reach thirty-seconds. This was how duels were in real life, very quick, brutal affairs. The player has many tricks to use against AI and Humans alike...

The player has three stances, high, middle, and low. Each stance has it's own advantages and disadvantages. They have different purposes and different uses. Unlike Nidhogg, where each strike did the samething. Players can also parry, lock swords, and even charge/jump backwards.

All bleeding, friend and foe...
...streams fading into river calm...
...Finally we are one!

-Ikeda Kanagonda

GRAPHICS: The graphics of Kiai Resonance are not 'impressive' according to the current standard. However, they are in my opinion, amazing. It is in imitation of traditional Japanese art and fits the game's theme and feel perfectly. It is as if watching an animated painting, objects in the environment move as well.

Also, unlike Nidhogg, this game already has working multiplayer. Complete with a ranking system.

Kiai Resonance is a 2D, 2 player (local and online) where timing and 'stance' is everything.

The game has a fantastic ambience to it, traditonal Japanese music and backgrounds: you do feel like you are playing hand drawn characters on cloth - I think the presentation for what is really a simple premise of a game is excellent.

You have 3 modes of stance: high, low or middle. These modes combined with charge and jump back can make the game fall into the twitch game category, as you must strike from your stance at just the right moment: there is clearly some luck in there as well.

Each stance is either a defence, counter strike or strike.

I've just spent an hour playing the 'solo' portion of the game and found that the A.I. can be beaten quite easily, This is not a criticism as it would appear the real attraction of the game is the online component, which incidently has rankings: however I could not match up with anyone online [the game is afterall new, and I sincereley hope that people go online]

The solo play is IMHO only available so you can get a feel for the stances and movement. There is also a section with challenges that will assist in your quest to follow Bushido and become the ultimate Samurai - these challenges, actually are quite challenging.

If you like these sort of fighting games, get it. However it may be prudent to wait until it has some online action, as the solo and challenges will bore quickly.

This is a very interesting and pretty little game with a simple premise. Samurai swordfights, 1 on 1, first hit wins. Its good at what it is, the problem with the game is that its very one dimensional. There is a bit of depth to technique as you get deeper into the game, but the game's lack of content hurts it from being something you will put a lot of time into.

Recommended on the cheap or if in a bundle.

A very good one-hit-kills game. You can make power shouts! Whoaaaaahhh! huuueooo!

Has amazing Japanese samurai art and is short enough for you to only focus on having fun. To bring you closer to being a samurai you can have a drinking game, a sip of sake each time you fail to kill your opponent.

If you manage to get all trading cards they offer beautiful and clean artwork in 1920x1080 (not a single watermark by the art creator).

After some hours playing, I have to say, this is a good game.

Challenges are funny, they don't take much time anyway but still entertaining, I recommed doing them first before playing online, but that's up to each one.

The singleplayer mode is for practice, since there is no story mode. There is also a local multiplayer for 2 players.

The online is really fun, but since the matches are user-hosted, if the player hosting has a bad connection lag can be awful, also, there are not much players yet, but everyday since its release there are more players on the scoreboard.

The visuals are beautiful, how some parts of the maps are animated, and some other are in a front layer, not all in the background, it really looks like a "living painting" with the warriors fighting. By the way, my favourite map is "Water" based on Tani Buncho's "Grasses and Moon" painting.

The soundtrack is wonderful, I think it suits every map so good (each map has its own), but things to be said, the menu song, despite being relaxing, can become repetitive to some, because it's a short simple melody, and if you have a long wait for an online match, you have to listen to it until you find a player (if you have music activated in the options)

The only bad thing I can say is that there's a lack of content, it would be nice to have some customization for the charachters, a "Challenge Editor" to make our own challenges and share them in the Workshop, more maps, for example.

There is one unlockable map, making them 4 maps in total.

To sum up, entertaining game, with more options than it may seem at first, it's a lot of fun when you learn "distracting techniques" and defeat a player with such tricks. The price is maybe a little high for the lack of content, but I do not think it is actually abusive.

It's one of those games with a simple premise that works in very interesting ways. Bonus points because I can pretend to be Samurai Jack.

Looks nice, sounds nice, but lacks content a lot and since it's basically a very quick and limited fighting game (rock-paper-scisors with addition of reflex), it can't handle the fact almost no one owns this game not to mantion playing it. Finding random players on-line is almost impossible and instead of developing a ranking system (which is pointless) it would be better to first make some more content and maybe then add the ranked duels.

There are also some interesting single player challanges (unique, quick tests) which can be very annoying since most of them are constructed like this: "you've made 90% progress? well too bad you diied and now you have to reapeat everything". Because of that trying to complete a challange requires repeating the same actions for 5 minutes and getting bored halfway through.

A cheap game but still not worth it's price (although you can get it in some bundle for like half a dollar). Feels like a free browser game with a unique idea but bad execution.

No magic, no ridiculously overpowered sword swings, no 9000 HP. This game is about simplified samurai swordsmanship, one strike, one kill. This game is about timing, precision and your own fighting psychology, just like Kendo (way of the sword).

As a Kendoka, I personally I like how this game peresents samurai swordsmanship: You have 3 stances, jodan/chudan/waki-no-kamae. Jodan is a very offensive stance, but you can't block. Chudan is the ambivalent stance, where you can attack and block. Waki is the most difficult stance, because it is a counter-strike and therefore must be very well timed (execute the strike when the enemy raises his sword for a attack).

Unfortunetly this game lacks hiki-waza (striking while going backwards). That would make taiatari more fun.
What I really don't like about the game mechanics is, you can only use certain strikes in a certain kamae. For example you can't strike a do-uchi (strike to the stomach) from chudan, but only from waki. There is only one oji-waza (counter technique) and that is nuki-waza. It would be really nice if there were sureage, kaeshi or uchiotoshi in this game.

All in all a great game, that would be even more awesome if there were more features (maybe a campaign/storymode?) and a working multiplayer.

Have to concur with the negative reviews. There is promise here; both in concept and art style; but there is barely enough here to constitute a flash game with controller support. There need to be more AI; more environments; just basically more of everything. This feels like a pitch for Greenlight or an early access game - not a finished product. Yes it's dirt cheap; but it's a difficult game to justify when Nidhogg exists. The only use I'll ever have for it is if someone wants to play local death match and just REALLY loves the Japanese water color aesthetic.

This feels like a stripped down 2d Bushido Blade. While that's not an entirely bad thing. Kiai seems to be missing a lot of the elements that made BB so damn fun.

There is no variation in the (only)2 characters you get to choose from. Sure that helps with balancing, but only because balancing isn't a thing when everyone is the same. However it kills the player's individuality & stymies gamer's creativity.

There are only 3 attacks & no options when it comes to fight or flight. Sure you can dodge back, but full on running away to lure the enemy into a disadvantageous position, makes for some crazy interesting battles. No projectiles, to throw your opponent off guard for a quick strike.

No limb damage, no jumping or using the terrain to your advantage, etc.

Content is lacking in Kiai also. Only 3 stages & like the characters, they're just aesthetic differences.

Online seems to be dead.

Look, I know Kiai isn't Bushido Blade & never pretended to be. My point is that Kiai is in the same vein as BB & while it does some things right, Kiai comes up a little short. The mind game & the quick twitch is there, but the variation in gameplay & content are lacking.

A good example of a 2d game that got a lot of this right is Nidhogg.

This is an ok game, but one to pick up on sale. Also it wouldn't hurt to have a friend that is into this kind of game as well.
