Thanks for documentation! So this is a safer version of the "hesitation-less" room 18 strat that Koala and I have done for like 2 years now where without slowing down to wait for a shuriken clearing and trying hugging the "inner walls/corners" of the switchback nature of the room to save frames. As you improve your skill in this rm 18 strat, recalling that spikes have a weird, but intentional central pixel hitbox, so you might get to a point where you cutting corner most optimally in which you touch the leftmost spike's tip while falling without dying, lol. This strat has killed many of our runs.

nice music choice
