First off, great game. I've never been the best at games like Getting Over It and Jump King, but I stuck with it and it was well worth it. I definitely felt like I was getting better at the game as I was going through it, so well done. That said, I do think it was too hard for a Game Jam. It ended up taking over half an hour to finish and, for someone that just wants to play a load of Jam submissions, it's not ideal. Also, looking at the other comments, I agree that it was very hard. So, as a game, it's really great, especially for fans of the genre but I think the completion time and difficulty will put off a lot of people just browsing the submissions.
