Which statement is associated with the line number that accompanies the error message?

My first guess is that one of your variable names is inadvertently the same as that of a typedef in one of the header files you're including.

It would help a lot if you enclosed your source code in CODE tags. That would preserve the formatting and, most importantly, provide line numbers that we could reference.

What compiler are you using?
The versions of C that I'm most familiar will complain if variable declarations are anywhere other than the first statements in a curly-brace block. For example, the declaration of level after the call to outtextxy() in function EndScreen().

You should convert the function declarations at the start of the file into function prototypes by specifying the argument types. For example, change "void Blast();" to "void Blast(int x, int y, int r);"
