Neat idea, the prototype shows potential.

Good idea!! with you work for more hours, that could be an awesome game

Great concept! With a little work it could be an interesting game.

It's not much more than a concept right now, but the concept seems good as far as I can see.

I would say though that I feel there wasn't a lot differentiate the "jump" in the game from a normal jump, it could have been "enemies attack when you jump". But saying that though, I got the idea around how concept used the theme, the way I feel is possibly just a consequence of it being short and there not being many mechanics to take andvantage of the concept yet.

That's actually a great concept! You have to really think about your jumps, which is pretty unusual in a platforming game. Also I love the art style. 
Good job!

Very good concept, you should return to the game after the jam and make more levels (And maybe improve the music, its a little bit annoying)! It's fun, well done!

Nice idea. As others said, quite short, but not a problem for a jam. Good job!

Way too short and simple in every aspect,definetely not bad though.Great song!!!

Nice work! Cool art and animations.

My first reaction : "I can jump"

Nice game, nice graphics =)

A nice game, art stly is very good but it is a very short also simple. Generally I like that.
