Really great work! So happy to find a new HyperCard game to play and it was a good one! Great job on the art as well!
I found a couple bugs:
If I go to the basement without getting the flashlight by remembering the code to get in from a previous playthrough I suddenly have the flashlight.
Whatever you're using to make the "Play-ay-ay" sound seems to crash on my Mac OS 9 machine, sadly had to play it in the emulator.
