Thank you for your reply, it is very helpful. I’m still working through the interesting examples, and learning alot. 👍  
you are right, the versions are a bit tricky. Since I once looked for hours for a “bug”, that was only related to a wrong phaser version, I always double check if I’m using the correct/latest version.

Would you maybe know about unittesting phaser code also?  
I just found some older threads like, but none have a template on how to unit test a phaser application:

- [How would setup unit testing for a plugin?](https://phaser.discourse.group/t/how-would-setup-unit-testing-for-a-plugin/7648)
- [Unit Testing](https://phaser.discourse.group/t/unit-testing/2922)
- [How do you approach mocking Phaser objects in unit tests?](https://phaser.discourse.group/t/how-do-you-approach-mocking-phaser-objects-in-unit-tests/3772)
