This was a lot of fun! It was an awful lot all at once though. Took some time to get used to just the movement and shooting. To have the lava, blades, and the switching mechanic all at the start was a bit much. As a suggestion, maybe have "phases" for the boss fights and introduce new elements as the health goes down? Just my opinion, of course. Audio and visuals were spot on as usual. And I love that Red is using Blue as the gun. Nice job.
