The greed fight was a bit hard to look at with the bright yellow and light blue. I think a little feedback that you are actually damaging the boss would be great. I also somehow killed Wrath after I died which was a bit weird. A few other people have said it, but I think background music would've helped a lot with the repetitive bullet sound and otherwise eerie silence.
With that out of the way, the Visuals were amazing, I love the idea of using the bosses names in attacks. The moving Sloth at the end made the fight much more dynamic and interesting (Ironic how it is the sloth boss that is moving). You did a great job with audio for your first time and overall nice submission
