not a walkthrough but I can tell you you can find diary pages hidden in the ground, or floating in the water.........and about red bricks...sometimes you have to do things...for example in the mine, but others you can find it when you break rocks or so...it depends, some are too easy, other takes a little time, but it's not very difficult. I've managed to get all the diary's pages (i had 2 missings) and all the red bricks. Get luck!
On the first right screen at the far right end you see a little monkey and then it jumps up high. I used a digger to dig up a note but couldn't find any other way to follow the monkey. Do I need to follow the notes instructions to continue?
It was very difficult but I beat it the 3rd time. First I made sure I was moving really fast except when up high on the ledge. I went after the ones on the right first and made my way up to the ledge. I carefully made my way to the 1 pillar up there then fell down to get the rest. As long as you have high speed and good balancing on the small paths you should be fine.
they're on top...you remember when you have to go through all the rails and when the carts coming down? and finally you have to climb a large ladder? after all of that you found the villian? there you can find the two carts...
Anyway, the note says something like 'get out and breath the fresh air, then jump 4 times to the east and you will land in the target' (something like that, i'm playing in spanish ...LOL)
