I tried both the NPC to help you get money, both are at $0 and cannot buy either, and all I was able to do is claim the game for free! I get you have 5, and 100 limited, however the way it is setup, I can't Pay or even gain access to get those perks! Sigh... I believe 100% off sales are global and affect even the perks too, except if at $0 it's impossible to buy them.

Hi Sarainia! thanks for your post, well the 100 sale should be on the game itself only however itch.io made the sale on everything so I modified it to 50%, i guess it will work now fine, thanks for your feedback :)
