Well this was certainly a trip. While I think it might have gone a bit overboard for me, I did appreciate how consistently the absurdism was applied, and the 3d and 2d blend together pretty well.
With 666 lives I never really felt like there was ever a reason to not just run straight through the level, shooting whatever I came into contact with. There also wasn't much audio/visual feedback for taking damage, so I never really realized I had lost a life until my character was replaced with a flashing respawn arrow.
