Welcome!
My tips would be:
- Map out your game ( there are plenty of free flow chart type things to use) : This will help you stay on point and not go down a rabbit hole of endless choices. Its wild how adding one choice can make you have to re-write 10+ pages down the line. This can also help with continuity across your story
- Keep the first story short and sweet. Ambition too early on is the noob killer around here. Make a small story. Get familiar with the editor. Maybe play with variables or an inventory system. When you feel comfortable publish your story.
- Use the forums. Sure we all like to shitpost and call people out, but writing is the main focus around here. Maybe you've written short stories in the past - post them in the forum. Ask for feedback. Maybe even ask people to take a peak at your storygame before you publish.
Best of luck!
