Welcome to the site. Glad you found something other than endless cam videos of dudes jerking it on Omegle, although I question the level of procrastination you're doing if you go there.
I'll give the generic warning that in regards to writing a storygame, good ones can take months of work, so you won't get much appreciation if you spit something out in a few hours or days. For shorter stuff, there's (I think) a monthly writing competition in the Writer's Workshop, and there's definitely prompts every two days or something that are usually quite good for just avoiding procrastination.
Well, anyway, I'm Steve, welcome to the site.
