I still have no idea how to do bullet sfx! Like... with a million bullets it just gets insane and unpleasant so I removed them. There must be some trick that shmups use I just don't know what it is. I'm thinking something like bullet sfx can only occur every x seconds or maybe theres a max number of bullet sfx that can occur at once and once that limit is reached it just recycles them. Didn't have time to explore this during the jam XD
