Thank you for your comment! I keep the price low because it's a strange system and setting, and hard to play online, so I didn't want customers to feel ripped off it they can't use much of the material, and pricing it (rather than giving it away for free) also lets me notify buyers with update emails. If there's enough interest I'll try to sell it in a POD format on Drivethrurpg.
Have a good day!
