Finally managed to get the sub 11 minutes on this category, but there's still a little bit to understand and optimize:

• Skipping a cycle on the Mosphe Trial by getting a better propulsion when going into the secret room, possibly saving enough time to reach the second rotating platform section in time to skip a cycle and hit all the platforms from the inside
• Skipping a cycle in the Ewar Trial with the door before the crab alignment puzzle, but this might be already potentially possible by skipping one cycle in the Water room, but this would also save a bit of time
• Skipping an additional platform in the Gravity room with the first gravity boost skip, I didn't have enough momentum to reach the platform that leads to the treasure room and I landed on the earlier platform instead.

The rest went very smooth and I couldn't be happier.
