This is more of a general note, but my internet connection apparently isn't the best, and at the end of some dungeons (it seems to be related to how long I've been in the dungeon) after the stats page it says it can't establish a connection to the server and doesn't save that dungeon. That means I still don't have the GG even after trying 5 times. I'm not sure how you'll handle saving in the final version, but I hope that this doesn't happen.
Side note: I'm not entirely sure what's wrong with my internet connection, as multiple downloads and other programs requiring internet access have never said I've got connection problems before, after or during the times I've been playing.
