I'm on the second trial now, back in desert land, have to collect 20 tears or whatever again.
I'm starting to get bored of the game. Please tell me there's not another recycled dungeon with the door relocked, followed by another linear dungeon in the same area with a drawn out boss fight at the end, all to be repeated a third time in volcano land :/
There's no other recycled dungeon in this game. The road to the fifth dungeon was my personal favorite, but of course, that won't mean anything for you. The fifth dungeon is less linear than all others, except for the last one. So you have one of the best stretches of the game ahead of you.
Unfortunately, the road to the sixth dungeon is much less enticing, even frustrating at times.
