Wow, you’ve made excellent progress!!
Few people who played the demo managed to find the Great Library! =D
In the demo, the Great Library is not yet an area open for exploration. =(
Your destination is the Petrified Forest!
You really need to move forward through the forest.
Go past the platform room and you’ll find a lantern. You must extinguish the lantern flames using your water magic and keep going! If you have any more questions, send me a direct message on Discord (gustavorochadev)
Thank you so much for your interest in the game! That really warms my heart!
Don’t give up now! I believe in you! ٩(^ᗜ^ )و ´-
Many magical blessings to you! ~・ﾟ⌒*:･ﾟ☆
