With Wart glitch, I improved my published run 182 frames. For this glitch working, I can't use the 6th vegetable hit Wart at first time, must wait 1 frame. Then wait for 96 frames and hit Wart with the 7th vegetable.

1-1 saved 44 frames with shyguy glitch. Desync on 1-2, because the enemy named snifit fire a ball and cause some lag.
