This is cool! Wasn't expecting the spoken word and singing halfway through the first track, but the acting is superb on it! Very unique take for a main game theme. I love the synths you've chosen and your placement of instruments in the mix is really cool. It reminds me of a modern take on an SNES era game, especially the second track!
The sung vocal & spoken word get a little lost in the mix at the end of the first track when all the instrumentation kicks back in, makes it a little hard to parse the lyrics. That's basically my only complaint about any of the mixing, though - you've achieved a really atmospheric set of recordings with your mix choices!
