I am working on Level 1 and am only able to open the “Ice Breaker” project. Why can’t I open the other projects?

In Level 1, as well as Level 5, there are required projects that must be completed first before you can begin working in the other projects. Once you have completed the required project in the level, such as the “Ice Breaker” in Level 1, you will be able to access the remaining projects.
