It seems like at least two (The Sun and The World) of your games currently use .rar archives. As a result, they don't work in https://itch.io/app currently.
Here's what you can do:
- Use https://itch.io/docs/butler/ to re-upload builds.
- You don't need to make an archive first, just push the folders directly.
- If you try butler and it's just not for you, you can always make a .zip file instead, and upload that.
- In case you used .rar because of file sizes, I just lifted the upload limit on your account, so it should work even for The World (which is bigger).
Feel free to archive this thread once this is resolved!
