×1. Press a plate with a mirror, run to conquer token & yellow door at (27,16) (and lure the adder). 1 step late.

×2. Let the adder move one step, press a plate, broke a mirror to let adder free and run to the yellow door at (27,16) (and lure the adder). Again, 1 step late.

×3. Block the adder at one of the hot tile and then try to kill it as fast as I can to release the pressure plate at (19,14) before the fuse pass it. I try different positions: adder's head at (19,12) and mirrors at (18,12), (19,11), (20,12); adder's head at (18,12) and mirrors at (18,11),(17,12),(18,13). Fourth mirror use to press plate at (18,10). Again, best I can do with sword moving is 1 step late. I feel like I need to strike every turn, but I can achieve this.

×if adders are blocked by their own bodies, they shorten.

×have the adder shorten by 3 tiles per turn. (once from sword stab, once from hot tile, once from "eating itself")
