I'm just starting a minigame for my little son. He is only 19 months old, but enjoys playing with a tablet and loves cars.
This screenshot shows the the current status of the application.
The app will be very simple: there is not collision detection, only some items to touch and make some sounds. I'm using QML for this and seems very easy to develop all the things I have in mind.
If I have time, the game will be available for Android for free soon.
