I just played your game.  I love the pixel art and music.  I especially love the title graphic.  The light coming down with the little girl and dog is very cute and engaging.  

The controls were a little awkward.  I'd recommend using the 'up' key for jump, and then choosing 2 buttons close together for 'lift' and 'stay' command.  That way your hands won't be forced  to constantly move around the keyboard.  

Some refinement to the items on the ground would be nice, as it was hard to tell what they were supposed to be, but that's understandable based on the time restraints you had to do the art.

I loved your artwork and story.  The graphics and music fit the tone of your game perfectly.  Great job!

Cute game. I like the pixel art and the mechanics of using your dog as a stepping stone. (That sounds really messed up, haha)

But I could not make it past the 3rd stage, the blue beholder guy keeps killing me :(

Also, the stacking of objects is not intuitive, as you need to precisely position yourself and throw the object.

But all in all, a short and cute game. The premise is interesting, and the presentation is great.
