Aka: The GG Shinobi. Looks like there is a 1 frame window where the player can jump off from the spike tiles without dying. Definitely useful for any TAS runners making a Tool Assisted Speed run. Obviously the audience in general may have never played this game so here is a brief explanation. This room is the 2nd last room in the game. The intended solution is to use Pink ninja's ninjutsu to freeze the proximity mines, the only downside is that you have to cast this at least 3 times. The second fastest solution and more reliable than frame perfect jumps is to use Green's double jump and then switch to Blue to use his ninjutsu to fly over to the other side of the room. This only requires 1 ninjutsu cast instead of 3 and you can keep 1 extra ninjutsu for the final boss by using Green's suicidal ninjutsu to refill health.
