There’s something you may not understand about the community you’re posting this in: Just about everyone here is already writing IF with one or another excellent engine that handles text and parsing much better than the Prof Strange engine does. (As you indicated early on in the thread, Prof Strange was written and programmed by people who aren’t actually familiar with the conventions of IF.)
So, when you post here, folks are going to be asking themselves what your engine offers that the engines already available don’t offer. From what I can see, while Prof Strange has pretty much nothing to offer in terms of text processing, there is one aspect of its interaction model that is neat and has real potential: the overlaying of text on the map! (I do see this in both Firefox and Chrome, by the way). If you found some folks to improve the design (typography and so on), and rewrote the engine to use native code to improve performance, I think you could have a pretty neat game, or series of games, built on this feature–in the tablet market, you could probably even have modest commercial success, reaching beyond the current market for the kind of interactive fiction that gets discussed here.
However, I don’t think that the map overlay feature is enough to build an author community on. It would only be practical for games with a certain ratio of text per location. Most games produced by modern IFers wouldn’t work at all using this sort of model for the interrelationship of text and graphics. In other words, I think it would wind up being an engine for producing Prof Strange style games, not for producing IF more generally. Maybe Prof Strange type games would become a thing, and in that case a critical mass of authors wanting to use the engine might appear–but they aren’t likely to be drawn from the pool of people already writing IF. That’s because, again, there are already much better tools for creating the sort of textual IF that the folks here are interested in. These tools are perfect, there are features that people would like to see available in IF engines that aren’t available today (see this thread, for example), but your engine doesn’t address that from what I can see.
In sum, I think what you’ve created in 72 short hours(!) does have potential, but not as an engine for existing IF authors.
(Edited to remove a bunch of first-draft stuff at the bottom that shouldn’t have been in there. Sorry.)
