How did you write so much in a week?!
There's a lot to like here. For me the standout tracks are the boss tunes, which have great breakbeat-action energy. And the ambient stuff isn't bad either. I would humbly suggest looking for things that might be trimmable from some of the ambient pieces in particular; as it is it feels almost like I'm watching a longplay of the game but can only hear the music, but that sort of cuts both ways; when things feel slow they may feel slower than intended, but I think the overall effect is positive.
The thematic correlation felt a bit weak to me but the actual dreamt-up project you put it to was excellently conceived, and I found it creative and very well-produced overall.
