Looking at the gameplay, Chroma Rush is a phenomenal app to kill time in line or in a quick car ride, or enjoy playing while in a waiting room or lunch break. It's hard to find games this practical and multi-functional.
I'm in a Color Theory class in my college, and this challenges me on the key things to learn in the class: tonal progression(which we started yesterday), value scaling, focusing when coming across simultaneous contrast, stuff like that.
And this fast-paced game helps spot things fast and gets me used to all of this, while having fun! I recommend this game to everyone, and you don't have to be good at art or colors to love this game. It's fun for everyone.
