The royal castle of the Kingdom of Arturus is just to the right of the Main Street on Astro Knights island. (there is an intervening ad space)
The castle of the Binary Bard is located on a giant asteroid in the asteroid belt (X-11 Y-82). You cannot go there until you have beaten all three planets in the solar system (Fire, Ice, and Jungle).
There is no way to reset an island. On Astro Knights, if you leave the island from space, the spaceship parks on top of the castle in Arturus. To replay the island, you would have to create a second username. You can have as many as you want, saved or unsaved.
One way is to go threw the hay near the mill, and the other way is to go to the castle, in the library,and find the book to the secret door

keep pushing it
You can't. The switch in the castle entrance only opens the small back gate. Later you can enter that way. (see related question)
you run into it and push then there you go
When you have defeated Mordred, the Princess knocks him out and you return directly to the castle at Arturus, where you receive a knighthood (the Medallion). The green orb is atop the spaceship fountain, so there is no way to return to Mordred's castle. Your spaceship, however, is parked on the roof.
Merlin cannot enter the castle during the game. You should go to the dungeon the back way, by pushing hard on the dirt wall to the tunnel.
Unless there is a costume for sale in the Store, there is no way to do this.
There is no easy way. (see related question)
It's only dirt. Push hard and it will give way.
The marsh is all the way on the right, go right from the Mill.
