The update looks good. I'll have to play around with a bit.
The sky and tiles look better but it looks to have loaded the older yellow and blue mbot model.

I noticed in the mBot robot kit video that there's LEDs and sound generators plus some other configurations and additional modularity. Will you be adding those as well?

This looks pretty neat. I've attended a handful of robotics/embedded/IoT short-casual classes and agree that it's difficult to get enough hardware platforms for everyone. Usually the class spends quite a bit of time finding pieces missing and parts not working that it leaves little time to focus on learning the key concepts. A hybrid class with many simulators even with limited amount of hardware platforms might really be the way to go to remove cost and time overhead while still keeping things adaptable to the real world application.

Thanks for sharing.
