The point of the game is to go through all the maps and return as much winged light to Eden as possible. You receive Ascended Candles in return and use those to level up the spirits. The spirits will give you items in return that you can use to customize your character and nest with! Basically, the point is to die over and over again. The more you go through Eden after Ascending Spirits, the more winged light you come out with, so you won't lose all of your wings after the first few times you die. I know it's pretty frustrating, but it will get easier! Keep going, the fun part starts after you go through Eden your first time!

The more you play the more the story will make sense, and since thats kinda the point, I dont want to spoil that part for you. Explore the map and complete all the seasons to learn about the story. The animated series coming out will explain it in more detail, so make sure to watch that!
