I played this during my Professional Responsibility in Computer Science and Software Engineering lecture! It was very responsible of me. Even though I normally do not play puzzle games, I still felt compelled to beat all of the levels in this one. And that is because it was enjoyable from start to finish, and I never got bored with the mechanics because you kept introducing new ones! I especially liked how complicated the challenge levels were—those ones actually took me significant time to think through and solve. I additionally find myself impressed with how you were able to design so many high-quality levels in such a short amount of time. I felt that the game was the perfect length for a nice session of puzzling.
