Art, style and interface are just incredible, stunning, perfectly calibrated and beautiful. *___* But not just art: music, game-design, gameplay - everything is breathtaking.
To be honest, I just can't imagine how you managed to make this game in a fortnight. If you ask me, you shouldn't have gone to that jam with it, you should have gone straight into Steam or another game store. It's already ready, interesting and absolutely professional, it's very hard to believe that you're beginners in gamedev, it seems that you're already professional developers. I believe you will take first place in this jam, because this game is just perfect.
