434 traps

But isn't that what happens on the NES?

I don't remember.... is it?

This is what happens on the NES. I just downloaded the ROM/Emu. Went into the L1 Bow room, entered, traps poofed and appeared, and left via the same exit, and the traps simply instantly vanished the moment I touched the side of the screen to scroll. They also vanish the very instant that you touch the stairs (Down to the bow/item room...) to warp.
