Now when you want to generate link to gd games
1st you are publishing your game which gives link with your game name then AFTER THAT you can generate new link with 1dsdqa2s1a213 which is for tests
I believe you did try to generate that link with random characters we used to get just for test
On purpose or by accident it does not matter but i assume you did
And you ended up with publishing it
I am describing issue related to it here
It should by default generate that link for test with random characters just for test
And not 1st publish our game then allow us to generate random link
