I got a black screen starting the game but could still hear sound. I'm on Windows 10 if that might be related.

I enjoyed the split screen/color coordination that was involved in this game. I would suggest a way to get back to the main menu or to exit the game during game play. I had to die a couple times to read the text at the top because it disappeared to fast. Nice work getting more than one level completed.

I remember when this little gem was called black and white.
Good use of storytelling and conveying meaning through gameplay.

Requiring the game to be installed and pushing people to make a donation, are both huge negatives as far as I am concerned :/

I really like your game. You only used simple shapes and colors but conveyed a lot of meaning and somehow made me care about the characters by the final level. To me it was because one side of the screen was almost always harder than the other. I wont spoil it for anyone but the ending made that meaningful. Might have been because I died so much I was able to spend enough time with them to form my own meaning in the characters and their actions. Great job and I hope you take that idea further!
