The art is really good, and the music is amazing! Congratulations on making the game yourself!
The game is quite interesting, but I found it difficult to understand how it works. Many times, I'd make a move and not understand why I'd win or lose.
Another piece of feedback would be to include the option to disable the letters' movement. This, combined with the rounded design of the main screen, gave me a headache after only a short time playing.
