A few days ago, I got a notice from Google that this zip file "allegedly infringe upon the copyrights of others." The zip with the 3dn file has been flagged--I don't know what that means--but it might not be downloadable in the interim. There's a chance Lumen will similarly flag the 3dn files for the other games I've worked with.
I've submitted a counter-claim of course, but we all know how long these things take, and the skewed chances working against smaller google accounts. There's a chance all three files will be permanently unavailable, and at worst my account entirely could be terminated because of this misunderstanding.
Just a heads-up.
