pretty good, i've got a suggestion though..
the interface with the higher than/lower than concept kind of made the game overly confusing to remember specific placement of the letters during the game.
otherwise it was kind of fun but the panda seemed to have a much larger vocabulary than i did and the concept wasn't executed as well as it could have been.
i'd honestly say this deserves a B+ for effort, however i do want to add that if you ever do a second game or change this one a bit it might be a lot easier if you had players type their word in the boxes for the panda to guess and have the game calculate the higher/lower on it's own behind the scenes, i admit the panda told me that my clues contradicted each other fairly often, wouldn't have been such a problem though if i wasn't counting the alphabet in my head the entire game repeatedly though :)
8/10 stars and 3/5 vote.
