This is an magnificent game for being made in just a few days. There are a lot of mechanics that are not necessary but they give a plus to the game (such as the achievements). The art is atractive and consistent during the entire game, which made it really incredible, and also the music fits awesomely the scenes. Regarding the story, it's very deep and well constructed, though there were some walking parts (specially near the ending) which were a little unnecessary, though they weren't boring at all.
I'd highly recommend the game as it's very innovative and fun. Congratulations!
