Full achievement guide with pictures to Candleman: The Complete Journey.
Introduction
At least it will, it is under progress because I am flipping back and forth between the game and editing the guide as I get pictures and also as I take breaks [there are a LOT of candles]. Please be patient, I am working on it. Or don’t be patient, I am not the boss of you.

Light All The Candles: Chapter 1
A little candle went to and fro:
This chapter has a total of 9 candles to find.
The first candle is the trickiest one of this level. The trick? Go backward. The moment you spawn, head backward and follow the path. The first candle sits in front of a mirror. 
The second candle you will see while walking the main path, out in the open. 
The third candle is found by climbing atop the chain to the right of the second candle and then onto the box.
Before jumping down, make your way to the left. The fourth candle is found on the box across a small jump.
The fifth candle is found out in the open, next to the checkpoint candle. You will have been able to light a total of 5 candles by the time you make it to the checkpoint candle. 
The sixth candle is past a small puzzle. You fill find a floating platform. Jump into the water, it is too shallow to hurt you. Push the platform all the way up. You will use the platform to get on the box at the end of the water path. The candle is just around the corner.
The seventh candle is along the path, not far from where the platform you pushed in the water was originally.
The eighth candle is just off the path, under the ramp to get to the end of the level.
The ninth candle is just before the portal to exit the level.
His tender flame shone through the dark:
This chapter has a total of 8 candles to find.
The first candle is slightly right of the path, at the end of a small plank.
The second candle is along the path, atop a barrel.
The third candle is found by going down when you hit the large box, just past the second candle. It is not far off the path.
The fourth candle is along the path, atop a barrel.
The fifth candle is atop the left box, while the path goes to the right. You will have to angle the moving board to jump up.
After the fifth candle, you will find the checkpoint.
The sixth candle is along the path, on a small box.
The seventh candle is along the path, just before the portal.
The eighth candle requires a bit more patience. Walk up to the angled board suspended in the air. When the ship tilts, the board will lower slightly. Jump onto it. Use the angle to make your way onto the large box to its left. The candle is on that box.
