It is a good puzzle game that does a good job of onboarding the player. I think it either doesn't match the theme or I failed to understand the connection. It tries to introduce some sort of narrative but I failed to get it.
Design-wise, it must have been quite a lot of work to come up with the challenges of this game and to get it done - if there was a game design category, I'd rate it highly. Also, the game worked well on my phone, I played it and experienced no bugs or UX issues.
