Loved the harmonic progression of Luftsoldat. The sample that comes in halfway through seems disconnected from the flowy tempo changes of the piano, which distracted me a little.
I can see myself strategizing with Command Room. Weirdly reminds me of the Breaking Bad soundtrack haha. I think some more low-end would be great here.
I like that you kept the theme from Command Room into One Man Army. The added energy is nice! And having Carri Armati e Fanteria be more foreboding helps it fit with the "enemy is winning" theme.
I liked the siren-esque sound at the beginning of Hikōsen no gekitsui, I think some more movement with the melody would bring even more energy.
Endkampf is great because it has the awesome main theme progression. Great energy, but like the track before, some more movement in the melody would be nice here as well.
I think Unsavory Bliss is a great track for the end of the game. It has a real "you won, but at what cost?" feeling to it.
Good job!
