So I've updated Infinity Saga! That's the good news!
I fixed the sound option for you all complaining about it. You now have a volume control option in the Menu Settings!
Now for the bad news :(.
Since I had to go into the main script and edit it, the older save files have been corrupted. That means if you were really far along in the game your saves before this update will not work. I'm sorry and I apologize for any inconvenience, but at least now you can adjust the music and sounds so that they don't make your ears bleed when you have headphones on.
I'm thinking about compensating you all for the slight inconvenience, so in the next update, I'll give you all something extra!
