Nice! I really enjoy being able to solve a puzzle rather than just guessing randomly to get information. It's funny and appropriate that multiple plays of the same memory game get harder due to negative transfer. I kinda wish the reward was a letter but without the position, at least after the first one. Right now, the puzzle part feels a little OP. Also, my word (I won't spoil) was one I'd never heard of before, and I have a decent vocabulary so that was a little frustrating.
