It's always interesting to see what kind of things will be in the next buttons game. I've grown attached to these kinds of games over time. It helps that there are a lot of different ways to play. Normally, a simplistic design would hurt it, but it works just fine here. You also have a great selection of music. I like how you can change buttons.
That doesn't really affect the gameplay, but it's cool to look at. I never knew touching buttons could bring about so many results! You know how to create variants of the same thing. While you're not one of my favorite artists, you're still good. It's nice to be customizable.
