It's a good concept for a spooky game. Ending worked well. I did find the waiting for text to appear quite frustrating rather than suspense building (especially in the first section) though. I know it's to simulate texts coming through, but the timer seemed too slow for me. It'd be nice to have the option to speed it up or click through to the next bubble.

Fabulous. The font and color change is a nice touch. I hope you expand upon it someday - so many possibilities.
