We have a few samples of uploading to itch.io here: Getting rid of the simulator for Itch.io - #9 by jwunderl, and it feels like it’d be relatively simple to create an app that was just a https://developer.apple.com/documentation/webkit/wkwebview with e.g. the output of the github integration (like this https://jwunderl.github.io/pxt-fireworks/). There was also this thread on computer builds, but I haven’t fully kept up with it Play MakeCode Arcade Game In App - #7 by Vegz78
@eanders I feel like I remember you playing around with this? Or was that just me combining pc compiled builds + other app store investigations in my head?
