I did find another skip on Vexation using that last canon. I timed the difference between the skips for each, and the clip (if done perfectly) is probably only slightly faster. The problem is the trick here is also fairly hard to pull off, though way more consistent then any clips.
Good stuff. Happy to see my old runs getting butchered by new strats.
I honestly wish that floor clip was never found. Makes a few of the acts so much less optimizable. If this game was actually popular I would push for making a separate category without the floor clips.
Game is super buggy, which I am fine with. All of the levels have very sizeable skips in them.
I don't know if anyone still cares about Vex 4, but here is a playlist showing optimized speed runs of all the acts. There are a lot of interesting skips and glitches that could make the game fun to run. https://www.youtube.com/playlist?list=PL4B-CMKEJpWTPE6wFBctBonlgW-rHhJRq
