Interesting concept, is a good platformer. I know that the frog jumps every X time but you could add an animation to be aware when it will jump. 

Very well done for a first game jam game. This is a great attempt at a platformer. That being said, trying to give you some feedback there isn't much i can say. However here are some thoughts. The music maybe needs some work. Although It fits the game it not that great to listen to. I had no problems with the controls or jump mechanics, however the controls could have been tighter. Well done though. I enjoyed it.

Hey, I tried your game out. I would have like to compare the old and new version to see how it improved. Anyway for the current version, if you still want to improve it, I think you could make some extra levels, as now it end when it basically starts (my game is as short as yours btw xD). Also I would add some visual feedback on your current boosts and maybe when the next jump will be.

Feel free to check my entry and tell me what you think of it. You can also compare it with the previous version as I left it in the download options.
