Thanks for the feedback!
Although music does exist and plays perfectly on my computer/browser, so maybe it's one of those which is causing the problem (or it could be some kind of bug, we'll check)
Regarding the cracking mechanic, it only happens when it falls from high places, so that the player must be careful about Stanley's health
Anyways, hope you had a good experience! :D
PS: Leaderboards seem like a very good idea, noted ;)
