Hey so i published a couple dumb games I don't want public anymore and is there any way I can delete a game I published?

No idea about deleting but you could edit the game listing and change the "Who can access this game?" setting .

It's fairly easy to make a game private.

I re-used an old picture. Just change it to "Only people I send the link to," not "Everybody."

While I'm at it, will it change the name of my game if I change it on that screen? I already piblished my game publicly. Pokemon Type Harley Johto and Sinnoh is too long.
