Such a cool vibe. I love dithering in any shape or form. :D The game is not too difficult, but I like the atmosphere and the concept. This version could easily serve as a solid foundation for something a bit more complex. :)
As for some critiques, I wish it were more visually clear which doors allow bringing items over and which do not. And maybe the walk speed is a bit too slow.
Great entry, congrats! :)
