Thanks so much for the detailed and kind feedback!
We have noticed that bug where you can get more than one queued call for a given user. We had actually tried (and thought we'd succeeded) to make sure that wouldn't happen, or if it did, that you'd be given enough time to ensure you could connect the next call, but it turns out we didn't quite get there haha. Hopefully something we'll address after the jam.
We haven't had a chance to check out your game yet, but I'll be sure to have a look over the next day or so : )
