I have a game coming on Itch I tried to go on steam and make it whishlistable but I had to sell my left kidney anyways, How can I Make people whishlist my game on itch

There's no wishlist feature on itch.io yet. We were talking about that on Discord just recently, but feel free to suggest it.

itch.io’s equivalent of wishlists are collections. If you add a game to a collection it will be placed within your library and you’ll be eligible to receive notifications about the game in some circumstances. (If you want to ensure you receive all updates from a developer then we recommend you follow them).

Hope that helps
