Neat little puzzle! Building a pattern that repeats down the card is a smart way to make punch cards into a game, and the second level with alternating rows made it click for me right away. The card flying past and printing looks nice, but waiting for the whole animation between levels slowed the flow, a way to skip it would help. Clean and easy to understand, nice work!
Nice puzzle and fitting to the theme! Knowing about shift/ctrl was exceptionally helpful. Your core loop is great and you could definitely build upon this mechanic
