If I knew anything about development for the Amiga Machine then I would offer to port it once it's finished, but I don't.
I assume you have a PC you will be able to run this on when it's done?
Rest assured, you'll be amongst the first people to get a beta-copy of this when it's playeable.
I'm planning on using mod-tracked remixes of music by Orbital for the game as well (all remixed by myself).
Title Screen - Orbital - Chime
In Game - Orbital - The Box
Boss - Orbital - Gravity Drive
Shop - Bomb the Bass - MegaBlast
