Love the isometric 3D and all round presentation of this. Not entirely sure it fits the theme, but I'll give it a pass due to how polished it is. Short, bittersweet story is a little on the nose for my taste, but it's a good concept and very well executed. Especially for a games jam!
Puzzles aren't all that hard, but that's really not the point. They don't get in the way of the story, and overall it doesn't ask too much of the player, which is a good thing. Nobody is expecting an epic 20 hour adventure in games made over 2 days.
I'd be very surprised if this doesn't make it into the top 100.
