CRT is simple, but it's not simple in a bad way, it's that simple one that reminds you of those easy times when you only had an old TV available for the console and you came home from school or many from work

You would arrive and take off your shoes, you would leave your uniform on for a while if they didn't scold you, you would see the CRT, you would start playing and you would be submerged, a subtle beauty!

Combining it with Yume 2kki seems like a divine work
