Yes, my offer to give any author an FTP site on my server (herbaloutfitters.com) still stands. You could use it to host your uncompiled games or even a whole website.
Also, I think I found a way to make images hosted on dropbox work. Just add “?raw=1” (without the quotes) to the end of the dropbox link. For example, change:
https: //dl.dropboxusercontent.com/u/100618/dropbox-get-link-screenshot.png
to:
https: //dl.dropboxusercontent.com/u/100618/dropbox-get-link-screenshot.png?raw=1
I got this technique from: http://cantonbecker.com/work/musings/2014/how-to-directly-link-or-embed-dropbox-images/ , and haven’t tested it myself. Let me know if it works! Looks like a fun game you’re making.
