My name is Sjoerd De Jong, also known as Hourences, and I have been responsible for optimizing all the art and levels, as well visually polishing up all the areas and ensuring the looks and style are consistent throughout the entire game. I also took care of the large majority of the PC to iOS conversion work. Tech/Level artist would sum up my work quite well.
I really like the atmosphere and feeling of the world. I have a weak spot for underground worlds and I have since long put a lot of emphasis on atmosphere in all my work. Unmechanical fits those interests perfectly.
