Press the space bar to increment the score by 1. When the score reaches 10, the score should be reset and the "game" should "level up" (i.e. change the background color). In response to a ScratchEd question: I've got 19 kids working on game projects right now and this is a common quirk: Many of them have a "score" variable and want to increment the score until it gets to a certain number, like 10, and then have the game advance to the next level. But many of them are finding that the "score" variable increments to 12 or 13 before the script stops executing and/or sends a broadcast to trigger the next level. Why is that? Is there a fix? http://scratched.media.mit.edu/discussions/how-do-i/slowness-loops
