Thank you so much for the nice comment <3 glad that it was a good balance of how punishing the setbacks were.
The music loop was something I added the last two hours before the deadline, so I definitely agree that it was a bit short, and maybe a bit too annoying for being that length. Music is definitely something I will focus more on next time :)
As you said, the time of switching between gadgets was made to not cheese the levels, but I hope that in the future I will be able to design the levels in regards to the tools and not vice versa.
