No idea as I haven't played bloody school, or indeed any of the japanese audio games, I was speaking generally about something I've noticed in audio games before.
A lot of audio games work on a simple reaction basis, whether that's space invaders sterrio targiting, pong, side scrollers where you hear something and hit or whatever. Basically the principle is getting a number of sounds representing the games objects (usually enemies, but possibly balls to hit, items to grab or whatever), and reacting asap.
What I would like to see more of is games that give you mechanics and positional information to make full scale judgements about. A great example is swamp, ---- you can hear where the zombies are, but it is only your experience and your judgement that will let you know your relative walking speed as compared to zombies, what weapons to use, how best to react, whether to skirt around walls or duck for cover etc. You need to fully understand the position of your character and the zombies in order to calculate your stratogy, and this sort of calculation only comes with practice.
Even in side scrollers, in the mainstream game world going back as far as marrio, it is this form of calculation that makes for the challenge, indeed in a game like marrio the very difficulty involves understanding and teaching yourself how best to jump, how long to hold the buttons etc, not mearly seeing and instantly reacting.
I know in audio it's less easy to show much spacial information of the sort you need to make these sorts of judgements, but as games like perilous hearts and the fps games show, it can be possible, ---- heck, even q9 had a little of this, although there I would've liked to see a bit more made of the vertical dimention and enimy attacks rather than simple closeness.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
