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!
