The colors do make it more difficult, but perhaps that's part of the challenge. My computer screen is about 16 X 11 and some of the game, the right side, is off screen. This happens with other games, too, and I haven't been able to fix it. My ignorance or the game design? This means I can't play certain parts of the games on full screen which is disappointing. Thanks for a fun game. I like games that make me think.
