Is there more after reaching home? I thought maybe you'd hidden some extra level in there somehow, but if not, still a fun short romp and great jam entry. You should be proud of your work.
I did hit one glitch when first digging for the key. I think I knocked my character out of the room boundary, because if I jump enough, I could affect the camera height, but I was nowhere on screen and couldn't get the camera to shift left or right:
Moving the boxes around with the mouse was fun and I think with some more time you might have worked out some other ways to build it into your level design to stack for platforming, or trigger switches or other things.
Good work. Thanks for sharing.
