Me (captaincola) and my 2 friends (DrifterDan and Darkone114) spent 6 hours on this. I have just finished it and it is located on world Guest29 if your would like to check it out in game.
The front gate (the arch between the 2 towers is accessible inside)
The dock (leads to a boat with an accessible underquarters built by me)
Throne Room (two staircases leading upwards and entrances to the castle towers on either side)
Top of the stairs (doors lead to large tower with balcony)
Top of the castle (zoomed out more than last picture)
Interior of one of the side castles (stairs lead downwards to throne room or upwards to roof)
Side garden (with small pool of water)
Thanks for reviewing this. I hope to have this made a successful addition to one of the main worlds.
Have a nice day now, cheers! ^_^
