Hey - thanks for the kind words! There's a big update due soon, to the itch, Scirra and Google Play versions of the game, which will add a significant amount of new content to both free and pro versions of the game. I enjoyed listening to your catalogue on soundcloud, and there are some tracks in there which are really close to what I want. Specifically I'm after industrial and military themed chiptunes, if you think you can handle that brief? If you want to keep in touch I'm @chilly_durango on Twitter, and the game has its own facebook page at facebook.com/rocketfellagame :)
Can't DM you on twitter, you have it set so you can only get DMs from people you're following. I saw you already posted the soundtrack update yesterday but I figure I'll send you the demo I made anyways: https://soundcloud.com/thrifstor/wip-3-1/s-rWLRH
Good luck on the game, I've been enjoying it so far.
