this game is really cute! i like the unique way of handling gameplay, it's like a reverse Words With Friends. i can definitely tell you got a bit limited with the one letter hints though lol. if you ever make this into a full fledged game with like the ability to gain user inputs on puzzles and things, i'd highly recommend just making the last letter be won automatically. or just animate a player character standing on top of the pile when it's on the two block stage, making the player the top of the pyramid. truly well done!
