Pretty sure skips are only things that involve jumping on the death barrier, but you might want to double check that.
The level 19 skip doesn't use a deathplane glitch but is still a skip. It's honestly kind of confusing on what is and is not a skip.
I'd say a skip is when you do a trick that allows you to skip over half the level i.e. jumping on the death plane in 6/10/27, jumping on the pyramid in 17, jumping on the volcano in 19, or jumping onto the middle area in 23 but I don't think the massive corner-cut in 22 is considered a skip but yeah skips aren't really well-defined
game update!!! load times are gone. yippee!! so a lot of runs will get faster and stuff
also, the in game time setting will (probably) be removed from the time settings thing because we dont use it and its a huge inconvenience for mods happy update !
