In flight - Awesome. Love that we hit the ground running. I think that's always a great feeling in a game. You start it up and -GO-. I'm getting an almost militaristic feel from this (I think maybe from the drums and the rhythm). Like we're marching. Love it!
In the cold - This one is good, but slightly overshadowed by the other two. But I reckon that was probably the intent.
When it gets too much - I really like those super fast arps and the melody line in this one. The melody indeed reflects a feeling of discontent very well. There's a lot of tension there. It sounds like we're heading for a mental breakdown.
My favourite is probably in flight. I love the energy in that one. The forward momentum is just too good to pass up!
Great work man!
