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.
