In this physics-based building puzzle platformer, you place the platforms and must then reach the top of your own creations. Help Bob through 42 meticulously crafted levels in his career from apprentice to architect by building the tallest structures imaginable.
Engineering degree or not, with your help Bob can prevail!
In each level, you're faced with new challenges and can only use a finite number of objects. Place, rotate and stack the objects to make them fit where you want and ultimately create a climbable structure that takes you to the top.
There are many different types of objects to build with and they interact with each other in different ways. After each level you will be able to compare your score with all who beat the level before you, can you get the top score?
Create your own levels when you unlock the level editor, send your creations to a friend or receive them from other players via our discord and play an unlimited amount of levels.
Feeling stuck? Have a friend send their solution to a puzzle or hop on over to our Discord server and ask for help so that you can get those tricky achievements. Your three best solutions for each level are always saved. Just go back if you ever forget how to get as high as your personal best!
