Great job on the tutorial overhaul.
It has become much easier to understand, and I learned a lot.
I was able to successfully proceed to the export stage.
Although this is not a bug, there is one point I would like to mention:
In the tutorial “ACTION GAME MAKER from Scratch,” Chapter 5,
when defining the parallax background, the image name provided for download is not mountain.png.
Additionally, the image size is 281 pixels in width, so the subsequent explanation stating
“Repeat Size: x=1080” did not result in proper repetition.
However, setting “Repeat Size: x=281” works without any issues.
