Cool idea for a game! I did get some crazy loud sounds from playing this game when the chains got ridiculously big. It'd be nice if there was a win/loss condition if you were looking to continue with this in the future.
When i tested it on my device it didn't had the loud noises. Probably it just operating system differences.
And you're right the game need a win / loss condition. I couldn't do it in 3 days.
