by Studio Mothmen

A surreal dream exploration game created for the "Dream Diary Jam 4" event and submitted as a traditional Yume Nikki fangame. Go to bed and dream of strange islands across distant oceans...

There are currently three islands to discover and one effect to collect. The game will be updated with more content in the future. The original soundtrack can be streamed here!

Yume Nikki is a game made in RPGMaker 2003 by Kikiyama. It's a weird and beautiful experience that you should definitely try.

When I go outside (at least I suppose that's where I am...) the world is pitch black with the exception of some rpg-maker-style drawn elements and the word "GIF" flashing in a corner. Idk if that matters but I'm using the Linux build.


Beautiful artwork in some areas, and everything looks great! I'm so confused but I get to wear a duck on my head so I'd say it's worth playing just for these reasons. Keep up the good work~


Thank you, we're excited to bring you more content soon! Eventually there will be more of a story and some mechanics which add a little structure so I hope it will be less confusing. We'll do our best ☆


Amazing work! I love how relaxing and beautiful the visuals are!


Thank you! We're hoping to get back to work on the game early next year.

My game doesn't work, it just boots up to a chrome extension with a file error that it doesn't exist? I don't think I fully understand what's going on here so help is appreciated. :)

That's strange, are you running it on Windows? Just double clicking the Game.exe should run it without issue

Yes, whenever I ran it it would open a chrome tab that said the file could not be found.

Sorry, I have no idea what the issue is! Have you been able to run other RPGMaker MV games with the same method?

I installed the latest version and it appears that it fixed itself. Still very weird that it happened in the first place

Sorry about that! I'm glad it's working now, enjoy and please let us know what you think of it!


Great work Eden, Tallin and Curtis! This is a really interesting and promising beta. I look forward to the addition of more places to explore and hopefully more interactive elements. 

FYI, I think I may have found a bug (though I wasn't sure if it was definitively a bug or not). Either way it's not a major problem. When you use the duck effect and then embark on the boat, the sprite which is used for traversing the ocean becomes the character with the duck on their head rather than the boat itself. 

Well spotted! I will fix that today, thank you for bringing it to my attention. Glad you liked the game, we'll be adding more content soon!
