This is such a fun, unique concept! Pressing pause to break the game felt very natural, I liked it a lot :)
I would avoid the pixel-precise platforming, because it takes away from the puzzle nature of the game. A good rule of thumb for puzzle games is that the time you come up with a solution and the execution time should be somewhat close (otherwise it makes every retry slow and players can get frustrated/bored)
That said, I would really love to see more. It was such a cool game, congrats on the submission! :)
