Very creative concept, and one that really blew my mind at how novel it was. Like many other commenters, the "T" had me stuck for a while, but the satisfaction from finally making the right combination was enormous. The presentation is a 10/10 with the relaxing music, intuitive interface, and well-written tutorial. Not to mention that players can submit new words, which is a great feature! Definitely blown away with how your team produced this lovely game in 48 hours. Great work!
EDIT: After completing the game and even making my own word (check out "AWESOME" with a score of 13985!), I love this game. There's the idea of simply finding the solution, but then there's also the component of optimizing for a high score. Suffice to say, that second component totally won me over after my initial impressions of the game (though I have to admit, I cheated by looking at the JSON file to figure out how to make 'S')
