Explore an empty world in search of something out of reach. This is an adaptation of the music video for Nanashi Mumei's single "mumei", using the minimal interpretation needed to make it coherent as a game. I also tried to stick to the order and direction of things that happen in the video whenever possible.


WASD/arrows for movement. Space, Z or J to jump. X, K, or E for picking things up or going through an entryway. Escape or Enter to pause.

Alt+Enter to go to fullscreen, though because I can't quite figure out how to get the game to play nice with a browser, leaving fullscreen requires pressing escape as usual and then pressing alt+enter to fix the view.

This game is best played in one session, but in case it's needed the game also auto-saves once per second when you're on the ground and not in a cutscene. Unfortunately bad planning resulted in the saves not being quite accurate. They shouldn't break the game though.


Based on this music video by 大鳥, for the song "mumei" by Nanashi Mumei and TKN: 


This is an unofficial fangame following the Hololive Derivative Works guidelines as best as I can discern. Hololive is owned by Cover Corp.

I also used some but not all of the same translation for english as in the subtitles for the video, but translation credits list 5 people with no further details so I don't know which to credits. Here's all 5 regardless: fts, Isara, Lamine, Sakura K., Hiro

I did the Indonesian translation (the bottom one in-game) myself, using Google translate and Wikipedia to deal with my lack of skill in that language.
