This project is a version of Llamalover's project, which is available here: http://scratch.mit.edu/projects/Llamalover/5677 I'm not sure if it helps solve some of the problems. One of the more major things I did was put the if-else block in Sprite 1 inside a forever loop. I also made it so that if Score is greater than Speed, a "WON" message is broadcasted to the world. This message triggers other blocks to execute (Sprite1 switches to a costume saying "you won!" and Sprite2 hides) Cool game, Llamalover!
