This ate three years of my life.
Butterflies is a game about inline skating and graffiti. Apparently some people did that before, but they don't seem like they'll be doing it anymore.
This is the first official release, an early access build of Episode 1. In it, you complete challenges, evade the cops and recruit a crew (original ideas, do not steal). There's also a challenge mode for the speedrunning-inclined. Those who want a taste of the gameplay can also play the free pilot episode, playable in the browser.
Happy riding.
