Howdy kalimag specifically.

Looking at the maps, 4-1 seems like the biggest map with no real skips right now (outside of rapidly climbing up the ghosts at the end).

Have you tried double jumping off that top platform and hopefully getting enough speed to nick the exit flag? I don't feel like there's enough time, but maybe???

I don't see any way to get over the upper death planes which start the death fade out far too soon, if it was just the bottom death plane it might be possible. Even when jumping off of the ghost the horizontal distance seems to long to make it past them.

Another skip I've been interested in is using the bounce pad in 5-2 to jump over the entire level with a couple of bounces. I'm sure it's possible, but I was running into the issue of falling straight through the bounce pad after a couple of jumps due to the high speed. During one attempt I clipped into the encased second part of the level, but it didn't seem reliable, and with the time spent bouncing and falling it probably wouldn't save that much time anyway.

Oof, yeah I messed with it and there's just not the speed for 4-1.

5-2 I ran into the same issues. Bouncing takes a long time, and getting enough speed to actually reach the finish causes me to fall through the bounce pad. Unfortunately there doesn't seem to be a way to trigger the teleporter in the second area from underneath either 😢
