Bottle Rockets is a sci-fi platform game by James Earl Cox III set to the song "Alberto Balsam" by Aphex Twin. A short artistic work about mothers, daughters, and space, it integrates a glitchy aesthetic quite well into the plot and gameplay, and will generally succeed in making those who play it feel all the feels.
Color theory, sayeth Wikipedia, is "a body of practical guidance to color mixing and the visual impacts of specific color combinations." Color Theory is a puzzle platformer where you play a color-shifting pixel-man whose hue lets him pass through similarly colored obstacles. Both teach similar lessons: You know that red and green make yellow, green and blue make cyan, and blue and red make magenta, don't you? You should, if you want to master Color Theory.
