First and for must I must say: Great job with the pun!
The idea itself is also pretty amazing and of course also how you implemented it. Very nice and easy to get into mechanic but the difficulty lies in the puzzle. And the puzzles were also at a pretty good level. I didn't always see a direct difficulty curve but that is just a minor side note. Sadly I sort of rage quit in one level, where once you solved the issues, you had to run around 100 times to move the crates, which was a bit annoying. Because one mistake led to another 100 steps to take... (a take a step back button might have helped there). But that is just one level out of all the cool ones I played so far.
I didn't get to the end, which is why I can't say if you introduced something with the ‘ctrl‘ key but until the point I played, I missed the useful part of being in/with 'ctrl'. But this is also a minor inconvenience in this otherwise amazing adventure :)
Good Job!
