Here's the whole code I've written
am supposed to have a cookie falling to get into a cookie monster's mouth
the cookie monster is supposed to be going left and right
if they crash the program stops
my first problem here is that I don't really know why the pictures aren't appearing
Need some help
Thanks in Advance :D
