Just a demo to show that multiple instances of a custom block could be running at the same time. Click on the orange cat and the count will increase. Same when you press up arrow or space. The second count will also increase when you press those keys and when you click on the black cat. However when you click on Reset the counts are set to 0 before the forever loops change the values again. The first count will increase to 3 showing that 3 copies of the custom block are running. The second count will only increase to 1 since only one copy of the 'increase-count2' receiver script can run at once.
