It's an incredible game in many ways and I enjoyed it, but I did come across what seemed to be a bug that prevented me from playing to the end.
I gave up when I was KO'd in one hit by the boss on stage 5 using a dual attack, and although I was using level-altered data...
During the holiday event, the password screen didn't appear and I was told "that's not right."
The intro to the event where goth equipment was required triggered twice (before the data was altered).
During the subsequent event where goth equipment was shown, I was unable to proceed due to the error log "Failed to load: img/characters/%24chocola%20g.png".
I wonder if other people are having success with the same event?
