It's not colorblind-friendly Currently  I have a hard time with yellow and green in the Flood game. It would help if the green is darker. But it would be the best if you added """"""""""""""""colorblind mode"""""""""""""""" for other types of colorblind. Many types of civil/electrical/mechanical engineering schematics can be drawn in pure black&white. I'm sure there could be different strips and symbols all around. But 5 stars regardless.""
