Congratulations on developing your IF platform! I wish you the best of luck. Here’s my quick feedback.
Most people choose an IF platform by playing a great game and saying, “I really like this game, and I would like to make another game just like it. How did the author(s) make it?”
So, when IF platforms successfully take off, they require an admirable story (not just a technology demo) to attract new authors. Historically, the first “admirable” story for each now-successful IF platform was typically either written by the platform authors themselves, or directly funded by them. (Twine’s first admirable story by Anna Anthropy is the only exception I’m aware of.)
You mention at the end of your demo game that “we’re not writers,” but I think you’ll either need to write something great or hire a great writer (preferably paid in advance) to launch Storealis effectively.
Writing the first good game yourself is also important because there are already competitive choice-based IF platforms out there, including Twine, Ink, Raconteur, and our platform, ChoiceScript.
All in all, your website looks great, and I believe you can build the community you want to build if you’re willing to put in the work/money required to write a great game.
