Really impressive environment work. I can't believe how much stuff you filled that house with! The theme and limitation were both very well integrated into how the game works, and I love the level design style where you gradually open up more areas.
Sound effects were really well implemented, but it could have done with more from an atmospheric point of view - either some ambient sounds, or a bit of music is the only thing missing. Implementing an inventory system was impressive, but I don't think the items wrapped on the grid properly - there were a couple of notes I couldn't read because they'd disappeared off screen. I'm glad they're in there, though, was fun poking around all the hiding spots to find them.
