I really liked this game. I think the only thing I can think of at the moment that would be nice to add is just more juice and polish. Like making the impacts/interactions feel more impactful :P. But that's only really if you wanted to work on it further after the jam as you can only really do so much in the limited time.
At the end I felt like I wanted more, which is a good thing! I was kind of hoping after getting into the elevator there would be a second phase, perhaps the boss comes out to say "oh no you're still not done!" and then you have some kind of final "boss" fight before you can actually go haha.
Nice job!
