I liked the idea, luckily i got through the first level :D
There are segments that give you a letter for free, but doesn't give you all of it's appearances, so it tricked me in one of the rounds. Maybe that should be improved, and some polishing
Yeah I designed specifically not to reveal all the existing letters to add a little twist there as well, but now by looking back maybe I should've opened all same letters at once.
Thank you for playing and reviewing though! I will definitely work on improving the game.
