-Travel and respawn timers only run while logged in. Not sure if that's a bug or intentional, but if it's intentional, then that's ridiculous.
-A bit buggy at times, but haven't run into any gamebreakers yet, but didn't try any of the exploits people mentioned either
-Runes don't really stand out on the spell cast screen. I'd suggest darkening the magic circles a little, to give the runes a little contrast and make them more noticable.
+Art is very nice
+Story so far is both predictable and unexpected, it's really a nice combination of both
+Tutorials are very thorough, though "follow the clicks" hands-on tutorials would be even better (though a bit more complex to develop, so maybe in the future?)
