Your games accept donations, and currently Itch is only indexing NSFW games that do not accept any form of payment.

EDIT:
The rules say you shouldn't ask how long it takes to be indexed, and there are several posts that explain the whole process. So, you didn't bother to read anything before creating your post. I'm the one who wants to cry.
