It's weird that sometime I play some jam games, where I am thinking that it's a really good jam game, but I do also think they could have done even better. This is one of those games. The idea is good, the graphics is well made, and the sounds/music is good and fits the game very well. But I have a feeling that something could be better, and I think you could have done better. I really believe that you could have done something that was more interesting, creative and fun, but instead you have made something that was simple and safe for you to make. I really think you have the talent to do more, and I think game jam is place where you could try to push you talent. Okay if you do that, there is a chance you will fail to make something that would be great, but I also think it would have given you a chance to make some that would have been really amazing.
When all that is said, is this not a negative criticism what you have made, because it is a good jam game. I will even say it's one of the better games in this jam. So what you have made is very well done, but I also have feeling, that you could have made something more interesting and intriguing.
