Arg... Well, I got about one day out of it (loved the game) but now every time I try to open it, it'll just give me a message in Japanese that says "Log" at the top and won't open. Tried replacing all the program I could find and it still does it.
Edit: The game was running invisibly and it was telling me in Japanese that it was already open >_< A quick trip to ctrl-alt-delete land helped. I get the fun of starting from the beginning haha.
On topic though one of the funniest cards for me was Mokou's second or third one, with the falling fire. I dodged it all without items (like you're supposed to) then for a minute I thought "Wow! I got her! That was too easy!' ...Of course I forgot she can revive.
