CC-BY4 allow user to redistribute (copy and redistribute the material in any medium or format)...
Reselling is a redistribution...
CC-BY requires credits but it doesn't mean that I can't resell because while I credit you I don't do bad... You wrote in the description that reselling and redistribution aren't allowed. But CC-BY allows any redistribution ...
It was made to be a "free culture" license (Follow the link because it answers your question). And as additional recommendation (after reading first link ) I recommend you to know what is "free software" is to compare with what you know...
About suggestion... I suggest you to choose license you want to use for this asset... If you decided to choose your custom license, you need to remove CC-BY4 from itch metadata because it is disinformation. If you decided to stick with CC-BY4, you need to edit description accordingly to CC-BY4 (And I recommend to add the name of the license)...
No, I am afraid it is still isn't synced with description :/
ND don't allow user to redistribute edited versions. All the CC licenses allow redistribution. So every user can share... NC don't allow commercial use so ND-NC would prohibit any selling (and use in commercial project :/) and redistribution of modified version.
Summary: No one of CC licenses "compatible" with current description... All the CC licenses allow redistribution each of them constrain "how" it can be redistributed but it is still redistribution....
