Mouse button won't work

In my new game Purple in the second level you have to click on a block to make it move into an outline, but when I click on it it won’t budge. I also tried replacing the behavior with a space button which works, but just using the mouse is something I would like to keep in the game.

I only see one level?

use a clock on the mouse click to repeat clicks

There are different levels as they go right (the value increases in the text as you progress)
