Thank you everyone for your suggestions! It seems that Itch.io is the best choice for the move currently. I was hesitant to use it at first because my game is being hosted there and I didn't want to find the bundles so easily alongside it. It turns out you can set your project pages to be "Restricted," which means people can only access the pages from a special password link. Anyway, all the bundle submissions have updated links, so if you're looking to buy those and help support me in the future, that's where you'll find them now! Thanks for reading, and if anyone has issues buying them on this front, let me know and I'll see what I can do.
