Inspired by Serial Experiments Lain, this game takes you on a surreal trip through a twisted virtual network. Uncover the secrets this world tries to hide from you: an artificial intelligence named "Fumiko"!

Fumiko! combines rewarding exploration with a new approach to 3D platforming. You'll quickly be unbound from gravity. No jump will be too short. Fumiko! is a sci-fi thriller that wants to be explored thoroughly.

In a single playthrough, lasting about 6-10 hours, you'll encounter:

  • 16 handcrafted and unique levels giving you a challenge, 14 social areas to explore ranging from small player homes to big public spaces
  • Enemy A.I.s seeking your destruction while you escape from the testing lab, unique abilities to bypass them
  • Fumiko overwriting her jump modules to gain ridiculous jump height, speeding through the air with the dash module
  • Collect 26 memory fragments to uncover the mystery behind the network
  • Supports the Xbox, Xbox360 and Steam Controller in addition to keyboard & mouse controls

Hi there! I just played through in one sitting on my stream and overall I liked it a lot! It seems though that if you play through in one go without closing the game the area near the start of of the final conflict where you rescue several purple viruses breaks. Instead of going up after being rescued they went kinda, anywhere else and this occured until I closed the game entirely and relaunched. Just wanted to make sure this was a known issue!


Just saw on a comment below that you're aware of it! Sometimes bugs are just unsquashable like that. Thanks for making the game!

That's great to hear that you enjoyed it! I'll try to find the VOD and watch it soon. :)

Yeah, that one is really weird and it seems to happen more than expected. Maybe the one-go aspect is an important detail, that might help troubleshooting.

Thank you for playing and your feedback! :)


Just stumbled upon this game - it's absolutely gorgeous. Beautiful graphics, sound and intuitive controls. Must've been a lot of work. 

Runs perfectly fine on my Mac running latest Catalina (despite what a user below wrote). 

Не работает на Mac.. Заходишь в Старт и всё черное(( 

i tried playing but when i went into the start thing everything was dark and i could only hear myself jumping. also i couldn't open the menu. is that supposed to happen? or am i doing something wrong?


Hey Ek3, I am not (yet) aware of a bug that causes this issue. It's definitely not supposed to happen - what system / OS are you playing on?

Catalina, which could be the problem - lots of games apparently don't work properly/at all on this version.

I'm sorry to hear that. Mac support is tough to do continuously, as you always need the hardware for it. With Linux, I could just install whatever distro someone is using and run some tests. Maybe you can boot camp a linux mint or windows for the games that aren't working properly.


Yeah, my roommate said I might be able to borrow their computer, which looks like my best option right now. Really wish I hadn't updated it, but oh well. Thanks anyway!


I am not sure if it is Catalina. Usually games that are not able to work won't even open. Either way, once I get a PC, I will definitely come back to this game and give a review.


"CAN'T YOU SEE YOU ARE CAUSING NOTHING BUT HARM" hahaha LOL that was crazy intro was like wtf is going on thought was 3D platformer puzzler xD


Wow, that was unbelievably good. It's seriously one of my favourite games I've ever played - graphics, soundtrack, cool story, fascinating use of scale with progression, fun to control, and did I mention, gorgeous? Other than using the guide for the Kronos puzzles, and having to quit/restart the Escaping Wilson #2 section (freeing the particles didn't do anything, and the opponent had no effect), it was surprisingly intuitive go go through despite how abstract it is. Thank you for such a masterpiece.

What a wholesome comment, thank you so much! I don't make much noise about Fumiko anymore, so people stumbling upon it and actually enjoying it make me really happy.

I know about this weird Wilson #2 bug but haven't found a fix yet. It tried debugging once and it was a weird chain of events leading to it. I thought I fixed it, but then it came back. I'm glad it's not a permanent thing, but bugs that happen randomly are usually the worst. :(

Thank you again!
