Man, what a great little game! The puzzles are very well-designed, the 8-bit graphics, music and sounds work great, and I love the gradual reveal of the memories. Seeing Game Jam games being well-written is truly a treat :)
Really the only thing I'd want is simply to have more of it; out of all the games I've played so far, this is probably the one I'd most like to see a full game of!
