Very nice! It was a lot of fun running around and shrinking random objects looking for secrets.
I wish I read how to activate an elevator beforehand because I fell down from a long section of outside pillars, too. 😢 Also, I didn't realize initially that scaling objecs takes power, but once I undestood that, I didn't face any issues with scaling.
Some kind of backstory about why you are climbing to the top floor of this building and why do you have this super ability would make the game more fun.
Great job!
