I played this game with a friend and it was super fun! Maybe even the most fun game I've played during this jam. The concept is great. Visuals are clear even with using only black&white colors. Were you also thinking about submitting to 1-Bit Jam that was also running last weekend?
As constructive criticism I would like to say that one thing that was really hard about the game, were the controls. The input system was really sensitive and even a really small change in how long a button was pressed could result in really big changes in how the characters moved. The interesting difficulty in the game was communicating different information and directing the other, and I think having too hard controls can steer the direction of the main game. I realize that some part of this was intended, especially in certain levels, but at other levels, you might want to consider adjusting the controls at least a little bit easier. Otherwise, as stated before, the game was great and really fun to play!
