Hi Jerry,
I'd recommend reading some of the top rated stories here, and having a look through some of the articles on writing. I really can't overstate how important spelling, grammar, punctuation and all that are for giving a good first impression of your story. https://www.grammarly.com/handbook/ is an excellent resource and I'd recommend giving it a browse and brushing up on some things.
Not too hard, simple storygame.
This is my first game, so please don't judge if its to bad.
You've got two mistakes right here in your description, for instance, besides it not telling anything about the story itself and making readers go into it expecting it to be bad. That makes people wonder why it was published in the first place, if it's something you're practically apologizing for and don't seem to be happy with or proud of.
All these are common newbie mistakes, so just pointing them out to help you avoid them. Personally I'd recommend just using that game to practive and familiarize yourself with the editor, and then not publishing it. When you're more comfortable writing, you might try writing out a more detailed plot and going from there. (Who your characters will be, what conflicts they'll face and why, the different paths the player can take to overcome them, and so on.) Basically just try and come up with something you'd enjoy reading yourself if you were to pick up a book.
It helps if you've written some regular stories in the past, but either way, don't expect to finish a story that's in any shape to post over a weekend. A good CYOA can take weeks or months. In the meantime, feel free to post samples of your work in the writing workshop if you need more detailed advice or feedback.
