qzecwx's video: Rockman 2 ONN part 2

Okay, hypothetical situation time! It's regular MM2 and there's a Sniper Armor approaching. You switch to Air Shooter, naturally (Quick Boomerang is a meme power :^)). Three projectiles come out at once, and because you're too close to it (and because Sniper Armors are bigger than Xoboxs) either two or three of them wind up touching it simultaneously. This interaction throws the collision detection for a loop, so the armor just glows yellow as if it's getting hit every frame, but without any non-collision frames in between, the entire string is only counted as a single collision. For whatever reason, a single Beta Screw Crusher can trigger this phenomenon all by itself, and this makes it hilariously inadequate against anything that it doesn't one-shot (so, anything that's not Pipi). Maybe it's actually two or three objects with the exact same positions and trajectories stacked together.
