I think that this version of spineworld is epic and i like how you worked but... here are my suggestions!
1.Add steam car racer link is here:http://mp01.migoland.com/dcr/games/ and (if you can't make meyan jungle place it in the cloud plaza and maybe add even minigames.
2.Please add some quests because it's boring without them
3.Please add pets if you can
4.Please add houses
5.Add membership buyable with 100 copper/month
6.This is the most complicated: add meyan jungle,beneath and dragon port!
Good luck!
