I've spent the past few months working on my music composition skills, and I'm pretty happy with the results. So far I've only made a few tracks for the early part of the game, but things should progress faster now that I'm making music with Speebot in mind, rather than random practice tracks.
I'm using SunVox for composing music, which is both a modular synthesizer and tracker. I highly recommend this software for anybody looking to make some tunes.
Besides adding the music I've also made some improvements to the engine and the game itself. I've fixed some long standing bugs, improved the UI and tweaked some sound effects.
Overall, the development of the game is progressing steadily, and I plan on releasing a playable demo later this month.
