I played it three times. Died the first, failed the second, won the third. The vibe was super creepy - like I got shivers down my spine. Well done. I saw you made the music yourself - very well done. The whole deal with the devil and the whispers layered was really cool.
The only issue I encountered was that sometimes I thought I dialed the phone and then I didn't buy the object and got penalized. That's how I died the first time. I couldn't tell if it was intentional or not.
Well done.
