Platinum Games posted another developer’s commentary video for Bayonetta where Hideki Kamiya, producer, plays through the prologue. Kamiya says animator Eijiro Nishimura hid a beetle in the graveyard scene and there are hidden beetles in Resident Evil 4 too.
So, instead of easter eggs, Nishimura’s games have "easter beetles" I… can’t recall seeing any of those in Bayonetta though. I think I was too focused on dodging attacks to trigger witch time to give the background much attention. Did anyone notice any beetles in Bayonetta?
