This really is a great game jam game. It's not long, overstaying it's welcome, it's not overbearing, but it doesn't fail to deliver a good and interesting story. It made me want to know more about Casey, which, for a small, first game, is incredible. Great job, great game :). If anything, cutting back on the gameplay to highlight the story I think would be better - the only bad thing is that I couldn't much enjoy the platforming, but I think if you improve the art a bit, that issue will go away. All in all, it's a really good game, and you should be very proud!
