Awesome job! Great music, great art, genuinely well-made puzzles- you got a tremendous amount done in the time frame! You did a good job designing the individual puzzles mechanics to be intuitive without using any words, and that is very impressive.
If I had to nitpick anything (and I do lol), some of the sound effects could be mixed better. Things like going through doors or toggling the red/yellow switch are significantly louder than everything else and kind of distracting. But overall, this is fantastic!
