Hey JayJay,
After you mentioned the image points, I went back and realized I'd made two mistakes:
1. My 5 loading images for "animation 1" were a different size than the one for the idle animation (animation '0').
2. None of the image points were set.
I was under the wrong impression that Loading in images in Construct would operate the same as doing it the default way. Not so.
I'm all set now :-)
Thanks, JayJay!
