That's great to hear! It's still experimental but we do hope to have good support for C3 on iOS in the long term. I'd be interested to hear how it goes if you use it.
I tried Construct 3 with my school iPad, and I can't get Construct 3 to link with my Cloud Saves, so there is no way for me to use it in a professional capacity yet, but this isn't really necessary for the students.
As long as we have a way to get images from photos into the game engine, we should be able to start making basic things. I teach physics, so I am interested in simulating movement and for kids to learn how to show movement as a series of position changes every tick.
Since all of the iPads now have high resolution screens, would it be possible to use the full interface, rather than the simplified mobile version? My students are used to working with their fingers on small screens, and I suspect they might have an easier time learning the software if the full UI were visible.
