I've run into a roadblock trying to get the basics of A5 going. I've determined a file exits via al_filename_exists, but al_load_bitmap continues to fail for reasons I can't seem to debug. My code is basically a mash of wiki tutorial code (doing speedhack '15). Scroll to "Test Grounds..." comment for relevant code:

Thoughts?
Edit: attached the image.
