Wow! Cool puzzle game that requires logical thinking skills. Level four was tough because I didn't read the level intro or press all the buttons on my keyboard! May I suggest leaving the hint on screen, perhaps minimising it to an edge of the screen for fools like me or eager beavers who simply skipped this most pivotal element! Other than that, the difficulty level/curve was satisfying and ramped up in a way that reminded me of other puzzle games such as Helltaker!
