<p>Does it have a lens cap? If so did you remember to remove it? We have all been there, done that, when using a viewfinder (ie non-SLR type) camera.<br>
Can you open the back with no film in, look through the camera towards something bright, eg the sky, wind-on and fire the shutter at all different speeds, to see if the shutter opens at all, and get a rough estimate of the accuracy of the times? </p>
