Jump 8 - You hit your head and fail far too often if you go fast, raise the roof please.
Jump 12 - Feels a little awkward because the space between the walljump and the speedshot is pretty short. You need to intentionally jump slowly off the initial jump and then launch yourself down pretty hard off the wall which doesn't feel smooth or natural.
Jump 14 - The ramp needs extending or pushing forward 64/128 units, I don't have enough time to fire a rocket after doing the pogo half of the time if I don't intentionally do it slowly. Also I don't think it needs to be nearly 64 units higher than the skips, it just feels like a clunky unneeded obstacle.
Jump 15 - Nobody likes double speedshots c'mon dude
Jump 16 - The tele feels a little weird. It's currently 128 units from the wall and 64 to the edge. I would make it 64 units from the wall and 128 from the edge.
Jump 18 - The stage number is missing, and lower the sync platform by 128 units.
Also on all jumps, keep the teles on skip platforms at 1 unit high please.
Really nice map other than those things though, I look forward to your other projects if you're planning something.
