I spent most of last night reading (and/or attempting to read, with Google Translate's camera function glitching and popping all the text, all over the place) through what I could find in Petit Computer's Help files.

The game can be downloaded using the Public Code 424JQK3NJ

Head into the top right projects thing, then hit R twice to access the Online games, then hit X (iirc!) and enter the PublicCode.
Job done!

WAAARRRNIIIIIIING
If you set up a Japanese account to download Petit Switch, be absolutely sure that you continue to use the Japanese account when coding your game.
DON'T do what I did, and go "Well, it works in my Jayenkai account.. I'll carry on with that"
Because, when you go to upload your finished game, you hit a great big wall..

I spent hours, yesterday, playing with Petit Computer on Switch.
I think I'm almost done with SpikeDislike, and the second session went much smoother.

Today marks the initial Japanese release of Petit Computer for Switch (PetC4) and .. well, I'm a coding addict, so you know I HAVE to at least get SpikeDislike up and running.
There's a few stumbling blocks.. well, one, really, and that is that I don't know any Japanese whatsoever.
