I've noticed that some developers release a game. Then delete it. Then release it again a few days or even the same day later. I think they do that because they want their game to appear on "new releases" again. If they didn't like your comment, they would've deleted your comment - not the game.
Viewing post in Devs removing games after commenting
They could have done that, deleted my comments, but deleting the game just because of the comments is a bit much.
And regarding deleting games to re-upload them to gain more visibility, the same thing happens on YouTube, they delete and re-upload videos desperately to gain visibility, but they achieve the opposite, because according to YouTube and its algorithms it is not practically recommended except if it is for the purpose of editing them.
