Nice concept, I liked the variety in the minigames! Are the questions/answers generated by the AI (I assume so) ? That's cool for replayability.
The platforming was extremely hard tho xD. For the barrel jumping one, it took me 5+ minutes to spell my first word successfully as I kept falling, and also rerolling would keep on not giving me the missing letter ahah.
The sound effects and music are both great, 10/10 on that part!
It didn't end up being an issue but... is there a way to type a word with a "c" in the chat? (since this is the key to close it ^^')
Overall cool project, good job :)
PS. Please try mine too if you have the time!
