Very nice work! This was a lot of fun and the number of features you added is truly staggering to me (number of enemy types, codex, aspects, etc.). The music had me head bobbing while playing and the graphical style and sound effects all mesh together very nicely. I definitely enjoyed playing it through all the way to the end, although it might have been fun if I had died at least once to try another aspect after unlocking them, before getting all the way to the end.
Excellent entry, congratulations!
