I noticed https://nightplaytv.itch.io/ has 3 projects that Still after a week are not listed. Even his last game ScineCraft II.

When will this be resolved?

There are three problems with your post:

1. Don't you think it's the creator's problem to ask this question?
2. There's a Search and Browse FAQ you were prompted twice to read before posting here.
3. I don't see why you had to create two different topics to ask the same question.

For what it's worth, at least one of the games you mention was published less than 24h ago. Indexing takes a little while at the best of times. Hope this helps!
