Hey, Scratchers! This is a sample repository to put Scratch projects into Android/Amazon Apps. Feel free to fork my repo and upload your own game to the App Stores.
This is the compiled repository with the source code of nathan/phosphorus and an index.html file linked to the Scratch project that I'm using as a demonstration. All you need to do to link your project is change var ProjectID to the number at the end of your project's URL.
After that, just use Adobe PhoneGap to port your newly-created web app to an .apk/.ipa file. If you have any questions, just check the official forum topic on Scratch. If you can't find what you're looking for, just post your question.
