I kept telling myself, "I'm not colorblind. I am NOT colorblind. I can see the color. You can do it..." My high score of 8 does not inspire confidence. (My day job include color calibration for paper prints, monitors, dvd disc labels, ect.) I ran this through my OLED-modded PSP 1000 -AND- PPSSPP. Sir, I hate your game, and I keep coming back. Grrr. I blame you completely. >:_D (Thanks for making this fun game!)
