My browser / operating system: MacOS Macintosh X 10.13.6, Chrome 69.0.3497.100, Flash 32.0 (release 0)
My project won't work in 3.0 but did work in 2.0. It should do exactly what the instructions say (it did in 2.0) but it won't now. When you press space it starts moving, but when you let go of space and it stops moving, you change the color or size (or both), but then when you hold space again, it doesn't move anymore. I have made no changes to the project. I am using chrome on a mac and a chromebook. Here's the link: https://scratch.mit.edu/projects/276380501/

I tried it and it seemed fine. I'm not sure if this is an operating system issue, or another problem. Maybe you can try checking your keyboard?
Or try an option or two on this list:

• Try again on another browser
  

• Click the project frame before pressing space
  

• Try on another operating system
  

Sorry for the issues.
