This is brilliant! The core concept is incredibly solid and clever, and the game teaches itself really well. The puzzles are designed nicely and the amount alone is astonishing for a jam. I had a lot of fun playing this all the way through and even did a few of the bonus levels. My only issue is that sometimes it felt a little inconsistent; I felt like I would do the same thing on two runs and get different results, which might just be due to slight changes in the speed of my mouse movement. Overall though, really well designed with great presentation, would love to see more eyes on this game.
