Correct. I'm currently working on a separate commercial use license folks can grab off of itch, I'm just trying to figure out all the contract details. I'm thinking it might be around $25 per set. Thanks!
I would offer a pretty good system to calculate a fair price (maybe even fair & just) if you like to hear. By that I would suggest you put the price up a notch like 30 - 40$ (At least I would pay that. Easily.)
