How to solve the puzzles and how to find the two secrets:

Secrets:
-Second cave, between the leaves
-In the forest, the corner in front of the cave exit

Puzzle hints and how to solve:
1. The color combination - The color combination can be found by solving the other puzzles. After you found out what the colors are, have them in order and press the left button (Wait a few seconds before pressing a button, to not break the redstone circuit).
2. The nether diamond - Its simple: the diamond shows that we need to think of something blue, that is located in the nether. This is a color combination puzzle piece.
3. The minigame - The minigame is not easy. You have to push the right button, that will take the purple concrete powder. Right after you pushed that button, press the other one, the one above the others. The timing must be perfect becouse the purple concrete powder will fall if this is not done perfectly. Now, the left button will push the concrete powder on the piston on the right. You have to be fast about this as well. After that, just finish the minigame by pressing the right button on the floor.
4. The lever lock combination - This one is easy. Count the heads of the wither on the left and press the correct lever. Then, count the lines from the middle block, then do the same as before. The respawn anchor can only take four glowstone blocks, so the number is four. You should now get the second color combination puzzle piece.
