Those items you see in the early screenshots will be added in the future when I enable the level editing and sharing system. I can't say exactly when that will be.

You might already have an account created. Can you send me an email at support@crashtastic.com with the email address you are trying to use to create the account?

Fixed in 0.4.7c

Let me see if I can reproduce this.

Good idea. I will add this in the future.

this will be part of the level editor.

This will be added to the sandbox mode in the future.

I will have an offline mode in the future.
