Incredible soundtrack ! First of all, I must preface that I am a big fan of MegaDrive/Genesis style soundtracks (I bought the Sonicware MegaSynthesis for this kind of sound recently, great tool) so of course I was going to like this and even then, the arrangements are really great !
Lots of nice variety that I could easily imagine being in a game from this era (it made me think of the Valis OST or Shadow Dancer on The Fortress Of The Black Dragon track).
Anyway, great job !
