Thank you so much! I added the script as game.c, set main to that function (in SED), and then ran it in SED. I should be able to continue with building and reviewing my levels now.

Furthermore, I wanted to say that I created an EXE after my initial post, and I could run the EXE and see what I had created (although I had no movement scripts, so I couldn't move around!).

But thank you for the help. That worked! Now I just have to keep SED and WED open at the same time.
