Personally I have a strange feeling about this game. What's with the weird sound effect in the video? Is that the only sound you have in the whole game? The birds in the background look weird and I would have make the farthest background picture move as well to improve the parallax effect.
I feel anything but "fun and excited" by the looks of this. It feels more like something for kids under the age of six. If that is your primary audience, by all means go ahead. If it wasn't, make it much faster (2-3x) and put some actual gameplay in it. It feels too static with no real challenges or rewards involved. Why would I want to play this game?

Also, you actually show two bugs in your video. When you first click "Start game" a balloon is already placed. Secondly, when the character dies it flies up but still triggers a balloon.

I am not sure if that is a development build or the final product. Either way I would like to say keep up the good work. I do agree that the game seems a little slow paced but it looks like you have a core mechanic which could become quite interesting.
