personally, the auto hints saved this game for me :P, as I totally got stuck a number of times and needed them.
May not fully agree with all the connections :P, but with plenty of connections to be made each round, it didn't matter.
Loved the story, music and art :), all came together well.
Right amount of levels for the story mode (and a Jam game length), and I saw after completing that you could play "main game" with new levels, which is great for those who want more.
Well done :)
