Update 5 includes new effects, new islands, and enhancements for every little thing!
Clouds have been added to the sky, dramatically improving the look of most vistas in my humble opinion. They also make the game a bit more comfortable to play for those who suffer from motion sickness.
Several new islands have been added too, including one from a new region! I'll be vague this time though, so that you can find them on your own.
Additionally, some tweaks have been made to how portals are laid out in The Nest, so as to better communicate and enable your opportunities for further exploration.
This is a nice solid update. There's no particular single change to highlight, just a lot of things falling into place. I hope you enjoy!
