Thanks for trying our game. The time was limited and we were not able to handle correctly the sound volume.
My comment was wrong by the way, what I'm actually doing is playing a sound only once (I even only play one sound at all) when multiple ships shoot at the same moment, the same sounds may be playing more than once as long as they didn't started at the the same moment but yeah that's probably not perfect, I've been struggling with that and you probably do better than I when you have the time ;) .
