So recently I was playing the Cornfield Crossing level casually on supertux mode, practicing for a run I will eventually release of it and while practicing I stumbled upon a few interesting glitches. If we find a reliable way to abuse those glitches, we might have a substantial time cut and a sub 1:30 cornfield crossing run possible. Anyway, if you are interested in seeing the skips, watch this video: Sorry for the audio quality, my OBS doesn't feel like working properly recently...
I am currently trying all possible angles in the artist debug mode to identify the ideal circumstance and so far I have been able only to reproduce the wrong warp glitch, no success on the far jump as of now.
Sorry for disapointing, I have managed to reproduce the wrong warp on the ramp, apparently the game has a checkpoint somewhere beetwen the shed I landed on and the ramp, meaning that this skip will not work. Basically, the lap doesn't complete and to verify the checkpoint we would most likely loose time and not have any gain from it. Same with the far jump one, there is a checkpoint somewhere. Still, what I have discovered in this video might add a few oppurtunities somewhere else where there are random rocks or meshes we can far jump off :-)
