It's a great concept, beautiful world and setup, enjoy the UI art, I like that it has an education vibe for children and adults can enjoy it as well, I would suggest add in meaning of the words we can click and look up after typing it in, and increase on that value. I see the game has a platforming aspect but the character movement still feel limiting, I wonder if you have plans for adding variety of movement to the character such as gliding and sliding? Those would make the traveling more varied and more fun for going around the big world you have.
I haven't really figured out how to get on the platforms yet for collecting some items, if I have time I will revisit.
