I just wanted to add to make it a bit more clear that Minotaur Rescue been tested and used and played quite some time in the previous months and quite a bit with the OpenFeint added.
Which .. seems to be a remarkable thing well done "clean and nice you put it in and does the job" and in all this time of testing we've been using it apart some little occasional 'server glitch' but quite rare we haven't seen anything wrong or such or 'so inetrrupting' to require extra investigation or debug.
Must be "our usual luck" of "launch the game and something goes wrong somewhere ( else ) exactly in that day"
What I am saying here is that if it did work that well during all the time we've been using it I suspect all this has to be some temporary glitch of the OF thing that hopefully it will go away soon, however if any of you having that problem would maybe post here a few extra info about what's going on, your system, etc. it could help me to get a better picture and maybe try to get in touch with the OF people to know something about.
I haven't put directly hands on the OF thign ( Yak did ) but IIRC he was saying it's a quite straightforward thing I mean "there should not be that much that one can do to make it wrong", if it hangs up "just even before to start" .. that's quite weird .. I mean for what I remember you call some kind of "Init()" and that should be all about it, OF is "not even used" until a score needs to be updated and such.
I'd go for the "OpenFeint too many people on the server maybe" way .. and/or I wonder if they have some "extra problem" now since they added the integration with the Apple thing.
