What an ambitious entry! I know how hard it can be to implement dialogue systems under these time constraints, and you've managed not only that, but some item puzzles, and an awesome elevator system to boot!
Love the art style and the sound design, and the writing still has me chuckling now that I'm finished.
The only real downsides are a couple of missing colliders, and the jiggling message window, while cute, might make it difficult for some people to read the dialogue.
