Thanks for your reply，Kepa！Those were just my random thoughts，in fact I think Renee is much playable than v1.0 already.
Automatically backstabbing closest enemy sounds cool，but may causes some confusion when you are surrounded by many of them，for you can't always tell which one is the closest. Maybe the current effect is just the simplest and best，though I still haven't beaten the gold dungeon ;p
I encountered some bug yesterday while using Abbie, with fire staff, not sure if anyone reported it before. I can't recall when it began, but when I noticed it, some layers of the graphics seemed missing. I don't know how to express it precisely(my English is not very good): all the flame disappeared, only the core of all fireballs remained. All shadow were gone. It seemed that only the basic graphic remained, while all other light and shadow were gone.
Sorry that I didn't try another run to see if it continues. After I restarted WS, everything was normal again.
