Among the projects I tackled since my return, one of the most interesting was Neon Star, by the French team ToxicRacoon. The music I wrote for the demo will be released for free on Bandcamp pretty soon!
I've also begun looking into alternative means of producing chiptune music since apparently this is a fad that won't go anywhere for a while! So I've become comfortable with Pixitracker 1-bit (pictured). The distortion is to die for.
