I really liked your interpretation of the topic.
Overall, the levels were designed pretty well. The assumption in the last level was good.
The mechanics are ingenious. The inclusion of the respawn feature (and the usage of course) adds to the games' complexity, paired with the restrictions on times each buttons were pressed.
My only negative is level 7, the blue text on the blue background is quite hard to see especially from a distance. Also maybe a restart button - although I could be blind.
