Gamestar Mechanic Challenges

I signed up for the Gamestar Mechanic Beta because of the power that I saw in ITeam members use of Scratch 1.4 to create games. Some students had a little difficulty with Scratch programming so I hope that Gamestar Mechanic will provide an easier on ramp to this kind of learning opportunity.

My invitation arrived and I have been exploring and asking older students to explore. They are generally enthusiastic and I am enjoying the opportunity to learn new skills and ideas. But I got stuck so I sent the following message to the Gamestar Mechanic support system:

In the instructions for participating in the Challenge you say

"If you haven't already, complete Episodes 1-5 of the Quest to earn the right to publish games in your Workshop. If you already have, you might want to replay Episode 4 for a quick reminder about top-down games vs. platformers." So, I know that there are at least three more Episodes to complete.

I have completed the four levels of Episode 1 and two levels of Episode 2. But now, the only choices I can make are to replay levels within Episodes 1 and 2. The colored indices display on the silos on the left of Factory 7 and level tabs (4 for E1 and 2 for E2 )but I don't know how to activate more levels within E2 or the next Episode. If that is part of the puzzle to be solved, then I'll keep searching for the key. If it is an unintended challenge, I'd appreciate some help in continuing.

Maybe I need a kid to help me through this barrier.
