Off the bat - kudos on producing 14 tracks!
This has some really cool ideas in it, and I adore the choice of synth voicings present. When I started listening to Legend of Xara I had it pegged as a standard chiptune track but the way it evolves and the use of really textural and expansive pads had me locked in.
The Title Theme explores a lot of really nice bits of sound design and ambience. This one is absolutely laden in moodiness and has an ominous kind of edge to it that is solely unique to this track. Big fan of how blown out and gritty that core synth beneath is as it continually flairs to life and then dies back again. Percussion in this is also a great example of less-is-more; does just enough to keep the rhythm, blends nicely into the background and fits the overall tone of the track.
My favorite of the bit-focused arrangements is probably The Director - it's menacing but also really catchy. A huge ominous introduction before kicking into the core melody (which I imagine playing over some dialogue) before finally getting into the gameplay around the half-way mark or so. Loving the choice of chords here and the accompaniment in the background doing a great job of bolstering those melodies.
Solid work all around - there's a lot to love here! Some really cool chiptunes mixed with some more modern sounds, all arranged and produced well. Great work! :)
