When you have allot in your game description, the site automaticlly adds a scroll bar to see all of the description of the game.
The bug is that this also translate to the editor and you can also see the rest of the description under the editor.
This isn't major and I've been meaning to post it for a little while now, but I already got a little custom to it.
This problem doesn't effect anything to the game, but it does get a little annoying to scroll back up to fully see the editor whenever pressing the open editor bottom.
Also if you click the description under the editor, the description goes to edit mode and fits the screen back on the editor. But when you come out of the editor, the description is still in edit mode.
Here's my game with the description;
