Hello!
Some things I thought would be very helpful:
1. Video/series of the basics of mobile development.
2. Creating a classic basic game for mobile (Fluffy-Bird, Snake, SPACE ATTACE, even Tetris). All the basic classic games with an interesting twist.
3. How to create a mobile version of Prot-Ninja from the lessons.
And I'm convinced there will be more to come 🙂
