Huje Tower is about building huge towers using organic materials. The materials used are the little hujos that come in a variety of colours with different abilites. The red ones for example are permanent once you place them in a construction whereas the green ones are movable. Yellow hujes are like glue creating new foundations on vertical surfaces. Brown hujes are heavy, and can weigh down structures at one end to raise them for example. The white hujes are essentially balloons letting you stretch other hujes, and lift structures.
