Why thank you!
It's really great to hear that from someone after two years :D
I won't lie, I really didn't even start to work on this DLC. I might never do so. The more I thought about it, I might just ruin the story if I try to extend it in any way. I know it might suck to hear that, but I am actually working on a new game at the moment called Neon Moon. It's over on my twitter.
Again, I'm really sorry to have to say that when you've been probably waiting for its release.
SoUnd Is ToxIc is not an over-and-done story. There is more to it, that's for sure. It's just that, it can't continue in the format of a game anymore (considering the story). So you might see a couple of novels written that explain the rest of the story after the events of the game. And those novels will be available when ready on my official site.
Thanks for being here, and I hope you have a great day!
