 ## Reporting bugs or proposing features
 Please, open just one issue for each bug you'd like to report, or a feature you'd like to request. Don't open many issues for the same bug or feature request, and don't use the same issue to report more than one bugs, or to request more than one feature. It's best to open different issues for each bug/feature request.

 Also, make sure to search the [issue tracker](https://github.com/Orama-Interactive/Pixelorama/issues) before opening a new issue, in case an issue like that exists. If you're unsure, feel free to open an issue. If it's a duplicate, we'll handle it.
 
 When reporting a bug, make sure to provide enough details, such as information about your Operating System (OS), Pixelorama version, Godot version (if you're using the source project) and clear steps to reproduce the issue. Feel free to include screenshots that might help, too.
