I'm a huge fan with people who uses famistudio, even though I never get how it works when I tried it
I loved the drums and bass that is always present in some of the songs, and how you sometimes utilize the noise channel for either supporting drumbeats and even sfx (the explosion for example is pretty fun). the game over theme is such a nice touch too and I don't see many games make this kind of themes for their imaginary games.
I never even heard of Turrican but I can easily compare it to an early Megaman game, great job.
