Thank you for playing and taking the time out to share your feedback. And thanks very much for the kind words on the VA.
On the audio clipping. I've done a little more investigation after the first report of issues and while the web export being single-threaded is the bottleneck; I have discovered there are definitely a few things I could and should have done better with the power of hindsight. It is a more general performance issue that is manifesting within the audio for the player on slightly lower end systems.
I was very conscious with the quantity of dialogue recorded with the branching and random bits of extra narration you can unlock, that the zip size would become too large, so all the dialogue, music and sfx are all stored as .ogg and this is really expensive to decode on the cpu. I should have used mp3 / wav for the sfx that's being played constantly.
I've also got a pretty terrible level layout considering I didn't get time to put any occlusion culling in, it gets better as you move through the game, but I really should have at least hidden some rooms until you come to them or got to basic culling setup. As in that first room there's probably a good 800 or so extra draw calls that don't need to be happening. OOPS.
Hope that puts a little meat on the bones - every day is a school day!
Thank you for playing and your comment.
