I don't think the music is the problem as I removed the said files and the problem remains. I've also downloaded the latest build and it still crashes if I press mouse button multiple time after the Unity splash screen. The problem is that after the splash screen disappears I can still see a mouse arrow so naturally I start clicking because I don't know what's happening and if I click more than once the game crashes. Maybe put some kind of "loading" text and hide the mouse arrow after the splash screen so one doesn't start clicking :). If I leave it be to load (which takes some time) all works fine.
