Very nice soundtrack, and also quite original !
There is a lot of great ideas in the different tracks, and the instrumentation flows together very nicely.
I also enjoyed a lot the tracks being clearly divided in two parts (like some Megadeth song titles) because you can quite easily imagine how to make the songs adapative in a game situation (with the second phase of a gameplay situation triggering the second half of the songs like in Metal Gear Rising for example), which is a nice touch in a Jam based on video games music composition.
Overall great contribution (with special mention to the vocals in the last song too), so good job !
