    beta build for music-cued visuals is available

    I took ~1 week off Astromino development, but I'm back! :)I've got the beginnings of a new system that cues visual effects based on music, because music is rad! but because it might not be stable, especially for Mac users, I'm publishing it as a "beta" build in Steam.you need a secret code to access the beta builds, SO: if you'd like access to the beta build, get in touch - all you early players know where to find me!once it's proven not to crash, I'll release a more-complete version of the update to the main version of the game!
