Like others said, the card part right? May I know does it take long to figure it out? My original intent is guessing people would take some time to find out what to do.
If it's annoyingly confusing (means not fun while you are figuring it out), I may do some fix.
Yes the Card part, after a few tries I found out that I have to find the right order, but I thougth "A" would be the last. The annoying part is the repeating dialog after respawing if you die a few times.
