Disappointing. If you want to make a good shrinking game or in your case, "interactive story" there has to be content. The length of this writing is too short and lacks detail. Just expand more on telling us whats happening. It is huge difference between saying "You are crushed" or "the weight slowly building upon you, your body is starting to give way, your bones creaking with every second that passes..."
There are a few spelling errors that need to be fixed.
Good luck at creating your game.
