There's a hard JRPG for you. It's actually designed for the purpose of making JRPG fans break down, whereas Chrono Trigger is probably one of the most accessible JRPGs in existence even to this day. :P
One piece of advice that will help in playing any JRPG is to try all possibilities. Usually in a well designed JRPG this can be done just by talking to everyone, but even if that doesn't solve the problem you can just try to find things you haven't done yet. Of course, I doubt you'll find such situations too often in Chrono Trigger.
