to be fair I had no real problem discerning things that much. It's just that the colors in themselves are very aggressive. I'm pretty sure a good balance could be found between the saturation and the hue. Although like I said you adapt to it after a while so it's not really that much of a problem anyway, especially given the time we have in a game jam so short :p.
My game have very basic textures stretched out on most walls because we did not find the time to adjust anything, what you did is way smarter for a game jam in 3D
