More than the simple fart joke I was expecting
The climb sprite bit with the guards not being able to follow Crono up the ladder was especially funny, and the Pink Panther theme in the church was a nice touch, too.
I can't remember that castle staircase scene where Crono climbs down a ladder a bit to let the guards pass him by and then doubles back (just before the bell scene). Is that background from CT? The Sonic loop just after the bell was a good idea, as well...
In a way, his actual fight with the guards was a bit of a let down after such a funny and well-conceived chase, but it came at about the right time. More chasing would have been funny, but there's certainly a point you were nearing where a lot of people might have gotten bored. Curse their attention spans! Good job!
