Rabi-Ribi: Erina phasing through spikes for some unexplained reason [Bug?]

Well, I legit have no idea what happened here. Maybe someone that knows more about the game engine can tell me how the heck Erina somehow managed to completely ignore these spikeballs.
Sadly, I was too shocked with this and immediately died to the green fairy anyway.

This wasn’t a one time thing either, I have experienced this a few more times since this video on this very same map... I believe it has something to do with the Quick Drop and the hitboxes of these spike things. Either way I believe there is some undiscovered potential here, if someone bothered to actually experiement with this.

You could also consider this as a small sneak peak of the next video, which will cover this Custom Map properly, as soon as I complete it- which, will likely take at least some days...!
