Avoiding a specific color (or colors, in general) is a gimmick that has been accomplished before — in Jayuff's "Strange Color" — but Subwoofer is able to infuse "Red Is Bad" with enough stylistic flair to make it feel all-new and refreshing as it revisits this concept. "Red Is Bad" is a pretty apt title. Touch the color red and you die. The level's complementary color palette, entirely consisting of shades of red or green, makes it visually appealing, with the usage of red and green almost making the level feel like a retro video game at times (with the malignant red acting like a virus infiltrating and invading a computer system). It's a level that looks pretty good, the gameplay is considerably fun, and the three coin routes (which all require separate play through to attain) are also cool! All in all, it's a nice level with a neat concept.
