How can I make lono level up from lev 20 to 30 I try many things and can't make her level up
Level 20 is her max at 0.0.9!
then this is the end of the game and I should wait for more updates to continue the story and unlock more characters?
It is the end of the update for Iono, yes. :)
Is there a rough release shedule for when the next update's gonna be?
We always take between 2 and 3 months aprox, maybe a bit more. Depends on the update.
