I am noticing you can work online, and download & complete offline, but you cannot, can you (?), upload an incomplete game for editing online from offline. Is that something that is in the works? Because that would be an extraordinary convenience.
No, I don't think anybody thought of that. 1 The online Squiffy and Quest editors only allow relatively few lines of code to be saved, anyway. As your game gets longer, the save button starts to chop off the code that goes beyond the limit. You should think of the online editor as a demo. New games are ready to play instantly. Re-uploaded edits only become available to play hours or even days later, so be mindful of that.
Yes, IF. You know, I've been doing squiffy for a couple of years and forgot that load-lag. I was trying to solve a problem by loading it into the editor and was baffled that the code was doing impossible stuff, like ignoring my write-to-screen tracking comments. Screwed with that for two hours, loading, loading, and finally gave it up in confusion and went to bed. At 4am, I woke up and the thought was in my head, "You idiot! The lag!"

Worth pointing out that I'm pretty sure this only applies to HTML games (including Squiffy). Quest runs on the server, so can't be cached.
