Gave your game a second play with the game link you provided in the comments below. I can see the potential of your idea and mechanic - my impression is pretty limited, though, as I got stuck on level 3.
For the visuals, I wish you would have kept the original style. Switching to a generic tileset doesn't blend well with the rest of the game. It is totally possible to hand-draw an environment your game deserves. This guy here has some awesome video series for such an approach, can highly recommend giving it a watch
The background music is nice, adding some more soundFX would / audible feedback for taking certain actions would be great.
