First time playing "Sky: Children Of The Light"

So one day one of my friends recommended this game (thank you!)

i couldn't install it yet because the storage XoX so i just removed some apps and i finally got it!!

And it's really amazing! i love the environment of the game, it's pretty soothing i think? (I don't know if it's going to stay that way the whole game "^_^) Also the story is pretty interesting, i wonder who's the first person to, like, live here...

The character designs are so cool! Capes are epic!!

And the music!!! I think most instruments i heard were the flute and the violin (Wait mabye that's what makes this game soothing)

I was kinda confused at first but i think i'm starting to understand :D

The only thing i'm annoyed about is my phone lagging out of nowhere T-T

Any tips?? or things i should do in the game
