Hello Khaled,
I watched some videos of your game, it looks really nice. I would be very interested to talk with you.
The extension update is not yet reviewed, but the project example is attached to this PR: https://github.com/GDevelopApp/GDevelop-extensions/pull/334
It won’t be as precise as in this build because it uses a feature that will come with GDevelop 5.0.125 https://github.com/4ian/GDevelop/pull/3417
I will say hello on Discord.
