About
In this 3D, story-driven platforming adventure, explore an uninhabited island's massive cave network. Learn about the heroes' psyches as you explore lush caverns, subterranean oceans, and surreal cityscapes, all while meeting surprising creatures! By Anodyne & Angeline Era's devs!

Use an acrobatic moveset to navigate lush, jade canopies and rusty sandstone spires. Fling yourself over high ledges using the satisfying Teledash Vault and deftly Wallrun across dangerous outcroppings.
Grapple through the air with the help of long-tongued Ribbats or climb tall cliffs via sticky-ridged Gripshrooms. Linking with certain creatures will grant you new abilities to reach the farthest depths of the island.
Research the island's unknown creatures by Linking with them! Using the one-of-a-kind "Puzzle Grid" system, overcome each creature's challenges by freely placing a series of colored tiles, forming large islands of one color.

In the near future, three biologists are on a joint mission to use their state-of-the-art ONYX implants to research the creatures of the uninhabited Sephonie Island. But as they approach the island, a sudden storm leaves them shipwrecked.
Amy Lim, Taiwanese-American and bold leader, hails from the midwestern USA town of Bloomington. Riyou Hayashi, an analytically-minded Japanese-Taiwanese researcher, calls the bustling Tokyo his home. And Ing-wen Lin, a kind and considerate Taiwanese scientist, lives in Taipei.
The trio will find their motivations and loyalties put to the test as they navigate Sephonie’s caverns, facing not only physical challenges but also their deepest memories and dreams. As they grow more intimate with each other and the island, an ancient force, brewing deep in the island's abyss, may threaten their newfound relationship, and the world...

A 6-8+ hour, one-of-a-kind, experimental, story-driven 3D platformer adventure.
Master a parkour-esque moveset to sprint, wallrun, jump, and fling yourself through Sephonie Island’s rocky and physical caverns!
A beautiful and varied cave system filled with all manner of large and surprising creatures.
A deep, emotional story about the close bonds of a trio, the priorities of nations, and the delicate connection of humans and nature.
The postgame “Bubble Adventure” and fiendish hidden items provide a fun challenge for advanced spelunkers.
A human experience crafted entirely by the IGF Grand Prize-nominated duo of Marina Kittaka and Melos Han-Tani, behind works such as Anodyne and Angeline Era.
Sephonie does not support square resolutions (Less wide than 16:10). Sephonie will run fine with these resolutions but some UI may be cut off, which you can fix by using the in-game UI Scaling option or by running the game in a 16:9/16:10 windowed resolution. The same goes for UWHD resolutions in fullscreen.
Sephonie only officially and natively supports certain controllers (PS4/5, XB1/XB360). Other controllers may work with Steam Input, but functionality not guaranteed. In particular the Nintendo Switch Pro Controller is NOT supported although players have gotten it working. See forum for details.
Sephonie has been tested to work on Linux with Proton, although there may be some lighting errors depending on your OS so we have chosen to not have an officially supported Linux version.

It looked like an interesting world set-up, and the puzzles were interesting. But the controls on PC are unintuitive, the floatiness of movement is awful. And the motion, even with adjusted settings, is unplayable for someone with motion sickness :(
坚持不开作弊打到最后一个boss打不下去了,虽然这个3d很艺术但是我玩着真的很晕。even the ocean是好玩的,但是可以探索的内容和美术都没有anodyne那么完美。anodyne2我也非常很喜欢,但是3d的部分对我来说已经有点晕了,但因为有2d缓冲和所以打完感觉还好。这一作我等了几年中文,因为这个系列有很多胡言乱语(褒义),所以我不是特别想啃生肉,不过好像制作组没打算出中文,就还是啃了。叙事和画面还是一如既往地好,但是难度+让我晕晕的3d没能让我一口气打完,一段时间没玩忘记键位就提不起劲了。可能以后有空会把最后的boss打了吧。下一作好像是俯视角3d,我还挺喜欢的,期待一下。总之会继续玩Analgesic的游戏的!
With very good music, a decent movement system, a decent story and a whole lot of collectibles this game is definitely worth your time. It's a bit rough around the edges though. For example, I got soft-locked once (but thanks to the infinite jump setting that was quickly fixed), jumping while wallrunning into more wallrunning feels near impossible, the story at times feels like it's not telling you anything whatsoever which weakens the overarching plot a bit and the visuals sometimes make it hard to find the right direction. The postgame is well made and makes for a fun last runthrough of the game. I do not really understand why the epilogue is not attatched to the main game though. A simple timeskip would've made sense too, but that's just my opinion. Anyway, great game, had fun, would reccomend
Big fan of the devs previous Anodyne games and was shocked when Sephonie was just as good if not better. The gameplay this time is on par with the excellent narrative and the atmosphere is incredible, really glad I got to play this game and it's sad to me how many people don't even know it exists, they're missing out on such a unique experience.
Quite boring, lots of "plot" (which you cannot skip btw) describing main characters that i dont care about and super weird and awkward controls.
The basic platforming mechanics in this game aren't functional. The wallrun simply doesn't work, it isn't difficult or complicated or janky, it just doesn't work. There is a section in the game that normalizes your wallrun and regardless if you jump early or late or anything inbetween including chaining multiple wallruns it is impossible to reach the other wall to continue. I did play on low settings, maybe there is an issue with that as i have noticed some other jank such as invisible walls / polygons sticking out on what appears to be flat surfaces. I even managed to fall through solid objects a couple times and also had my character just run in the air multiple times. There is something truly wrong with this game. Besides the game not working the story is also not fun, they hit you with a wall of text about about Taiwan and self-doubt after every platforming section. The only kinda enjoyable part of the game is the tetris minigame, except it is way too easy.
highly recommended no one is doing it like analgesic
an intensely beautiful game with really incredible movement. The movement controls are unconventional (and if you played on keyboard like I did God help you just use a controller, do not be as stubborn as I) but please dont write the game off so quickly as a resulty as ive seen some negative reviews do, the freedom of the movement system is pretty astounding and the game's tolerance for going to what feels like "out of bounds" areas is great, and somewhat encouraged. I also think the story is incredibly beautiful and worth experiencing, it's a lot fo reading but wha post-Anodyne 1 analgesic game isnt lol it's a shame this feels underrated compared to the rest of their catalogue, please give Sephonie a shot!
It's the most lovable game. Period.
Another impeccable Analgesic game with fantastic and thoughtful story, music, and vibes. The controls are a bit untraditional but once you get the hang of it the platforming is really fun and it's enjoyable doing parkour to zip around and explore the depths of the island. Favorite OST track: Chasm of towering oak
