Wow, I am impressed with this soundtrack Eetu! Great work here. I loved it. It reminded me of those old space shooters on the NES. Each song had enough variety in them to keep it from getting stale because a lot of it starting blending into itself as I listened. I really liked the textures you got with the synths. Very beating but also rhythmic! Lots of energy, that much I can say. I believe this came out better than you thought because I liked it. It was good.
Take care! Always fun to listen to your tracks.
