Um that's when this thread was posted.
There are two types of keywords you need to cover.
The first is word of mouth, and you pretty much have that covered with Scirra, and Construct.
The second is for search engines so yeah game maker would be a bit tough. Thing is you can add key words like "killer", "better", "similar", "open source", and even "like". So when people search for "game maker", and then they see "Game maker killer", or "like Game Maker", you can get better results, by simply filling in the gaps the other engines miss.
