Fun idea to make a sequel! :D
There's great emotion in these retro tracks, you managed to capture my attention straight away with the melodies and how these songs were put together. I think these tracks are a testament to not overcomplicating things, you use just enough melodic elements in your tracks, and you use them well through-out the entire piece! An approach I want to adopt myself. :)
Moomen sounds really nice when it kicks off at 00:26, so punchy, and that bass! And then the sax-like melody, mh-mm!
Really nice boss vibes in "Lunex Strikes!", I like it jumps between "oh dayum!" and heroic, feeling like sometimes we have the upper hand, but overall Lunex is doing a fine job of beating us up in return.
"WiSHMASTER's Dwelling" is a really cool track (darned be me and my understanding of music lanague, I can't express myself in more detail), being a demo, the fight is unresolved, the track itself though, is full of resolve to continue.
Sincerely, awesome stuff! Kept me engaged through-out the whole thing.
