Hi. If you have purchased it, it should be in your Library.
I have the receipt but for some reason its not there, it was for months but now its not, if thats the case it might be a technical issue on Itch.io's end but it's saying that it's not there no matter how many time I check. If this issue is out of your hands I understand and do appreciate that you still took the time to respond to my messages, thank you.
