The Juno Demo is intended for players to test out the battle system. The music and certain elements to the introduction are placeholder.
The game demo is set for open world exploration and as such, beyond the introduction, there is no story to truly progress in.
There is 1 boss and area to explore besides Nexus City.
Enjoy!
This is the rune board system which lets you customize Juno as uniquely as you wish. In the demo, you can buy the runes to modify HP, POW and GRD.
Crafting is different in this game where, unlike other games where you have to simply collect items and you get the item with RNG chance or just get it pop out at you, in Juno, you can work on it whilst crafting. In the demo, you only get the item after you successfully meet the essence requirements whereas in the full version, you get the item + bonuses based on how far beyond you go beyond the essence requirements.
This is the battle scene. You have free movement over the red area whilst the enemy holds the blue area. Using certain skills, you can modify the battle arena size from 3 * 6 to 4 * 8, steal enemy area or have your area stolen.
You can use union of which three are available in the demo once you find the NPCs, to gain unique skills and stat bonuses (stat bonus not available in Demo.). Be warned, once you unify with another character, your own skills are sealed until it wears off.
A graphical and textual explanation of this system is available in game.
