It was really fun and the presentation was nice (especially audio).
The puzzles were great too, I really had to think about it sometimes (still stuck at "Up a notch"). Sometimes there were elements you could drag in that didn't feel necessary (like the Skipper which I only used from "Up a notch" but not before).
And as another commenter said I think some UX improvements could elevate the experience (being able to remove a placed element, not resetting all the elements every time you make a mistake).
Other than that I had a lot of fun, great work!
