I'm gonna preface my comment by saying that chiptune music is not really something I'm familiar with, so take my feedback with a grain of salt.
I think you did a good job at making this album feel coherent in tone and composition. Each track contributes something different in the submission as a whole, yet their instrumentation is pretty similar. I can hear this full soundtrack playing in an old-school RPG or something similar. I liked that you attempted to put together music with odd time signatures, especially on 'Uncharted Territory'. It really helped keep things interesting.
With that being said, my main critique of this is that I would've liked to have heard some additional instruments or textures at some point in this submission. You change it up a little in 'Warp Drive' and 'Stranded on a Desolate Planet', but I think my ears wanted more variation still. Maybe that's just the nature of chiptune music, I don't know (again, not very familiar with this genre).
Also, in the future, please have the URL link go directly to a playlist where your work can be streamed. It makes the rating process much easier.
Thanks for sharing this, and keep up the good work :)
