I saw in https://blitsgames.itch.io/jock-studio that there was a $59.99 "PLUS digital goodies!" option, but there is only one purchase option for $49.99 in https://www.blitsgames.com/product/jock-studio-pre-order/. If I want to purchase a purchase containing "PLUS digital goodies! Can I only buy them at https://blitsgames.itch.io/jock-studio? (I want to buy "PLUS digital goods" on www.blitsgames.com!) ）
