This seems to me like a game that was supposed to be a lot longer and then got cut down due to time constraints. There are many rooms but only 3 that are good for anything. There is hardly anything to interact with, just people (most of whom are useless) and one object.
The art is good enough to see what's going on but not great. It's so scribbly that it's kind of confusing to the eye.
The music is not particularly noteworthy but at least it has music and that's something.
I found the puzzle unintuitive, and eventually just solved it by dumb luck going around and clicking everything.
