Hello neurons. I've been having fun the past month.
I have anticipated the project here:
#1235327123527565364 message
And as @storm peak suggested me I've made it into a Rhythm game, the same way I envisioned it on my follow up response
If you want to jump into it, here's the ip grabber provisional URL:

(jk btw, there's no analytics, shady backends or whatsoever)
This is still a WIP suggestions for features are very welcome!
.NUERO file extension
The game works kind of like OSU, there is an editor, a collection of songs, and a custom file type. the .nuero file extension represents a Fumobeat (song map), you can import them in batches by dragging them into the game, they will carry the song file, the beats timing/direction and some metadata like creation date, author name, etc..
Fumobeats persistance
The Fumobeats you see on your playlist will stay there when you leave the browser, they are saved on disk (managed by your browser's IndexedDB).
How do i create a Fumobeat?
Drag and drop any .mp3 file into the game, you will then be moved into the Editor mode.
In the editor mode, you can:
- Change the name of the song (by clicking on top-left text)
- Change your name (defaults to "Anonymous mapper")
- Play/pause the song, change volume and playback rate
- Clicking on the soundwave will change the time precisely
- Pressing Z or X will create a fumo
- Holding the right mouse onto a fumo in the soundwave will delete it
- You can also delete previously placed fumos with CTRL-Z
- The [arrow pointing backward] button will reset the playback rate to normal
Once you're done editing, you can save the fumo to your playlist, or export the nuero file.
Please, let me know what you think and of course I'd like it very much if you shared any Fumobeats you've made 
No fumos harmed in the making.





probably those could translate pretty well
