I've known about the site since last year, and joined, forgot my password, username, and email I used. But oh well here I am again. I don't know much about the site. Please fill me in. Do you make your own platformer levels on here? And can you play in multiplayer with others on these levels? Thanks.

you can make games on the ingame editor and post them here for everyone to try. Some people just make ideas, props or characters. animation capabilities and a monster editor have just been added. I think Multiplayer is intended for the finished version.

That sounds neat. So basically here we just make our own platform games, am I correct? I like the sound of it.
Also I thought the cost of this game was only 4 or 5$? Did it raise or was it always 15$?
