Of course, you could only be sure by inspecting every line of code in there. There is only one line where I make a local reference.

use lib 'C:\Documents and Settings\Ben Garvey\My Documents\spintris\li
+b';

That was so perl2exe could compile the thing. For some reason it can't compile it if you use a relative path even though it works fine through the script. To get start.pl to run properly you'd have to change it to this for your system.

#use lib 'C:\Documents and Settings\Ben Garvey\My Documents\spintris\l
+ib';
use lib 'lib';

The executable is for people who want to try the game out but don't have perl and all the libraries installed. There are no self-unpacking files. There is a zip file that puts files into directories when installed, but only sub directories inside the one you unzip to. Lastly, the program is for download on a website that has far too much personal information about me to allow me to get away with anything nefarious. Feel free to call me on any evil code. It's all there to see.
