Hi Scot and welcome to the forum.
I confess I wasn't fully aware of the circumstances with the vr gameplay, and unfortunately basic, reactive audiogames have sort of been the bane of the genre.
I do find the idea of analogue physical movement combined with fully immersive audio an interesting one however, sinsjust as a person in mormal space tracking sounds will use their bodily position to estimate where sound sources are relative to them, so the same is true for analogue physical control in audiogames thus providing an extra layer of information not possible with basic keyboard inputs.
As to games to try, you mention Pappasangre, however have you tried Somethinelse other title Audio defense zombie arena? It's a pure arcade zombie shooter where you are surrounded by zombies an need to kill them with various weapons. What however makes it unique are firstly the fact that the zombies have been coordinated for tactical play, eg, if you take out one of the farty zombies that explode it'll take out some of the others, and the weapons you have are best used to complement each other. Secondly, you control the game with the gyro on your iphone and a set of headphones, meaning you need to physically turn! towards the zombies and shoot.
I was quite impressed how I found my physical movements matching gun techniques in the game, for example I quickly learnt that instead of trying to turn my hole body to take out zombies close buy, I was better holding my phone between two hands and moving it like a gun to take out different targets, and only moving my feet when dealing with threats behind.
Swamp is certainly something I would highly recommend as well. It is the first ever fully online audio multiplayer fps, in which players are in a town over run by zombies and must slay them. it has cooperative missions, loot, solo quests, different sectors and all sorts of fun stuff, however one very unique thing is the use of mouse for analogue control of your movements and shots, so many techniques from strafing to circling are possible.
There is a huge variety of other games available, from audio stratogies like Time of conflict and
Castaways to Flight simulators, racing titles, and even a couple (literally a couple), of audio rpgs, although there are destressingly many arcade reaction titles too, however in terms of their interesting control methods, audio defense and Swamp would be my first recommendations.
use the "gamelist" link on the front of site to find the database entries for the games.
Hth.
I'll be interested to see what happens next in terms of audio Vr, indeed Aprone the developer of swamp is I believe working on similar projects currently.
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.)
