How can I beat this Dev time in Offspring Fling?

OK. I kept digging, and found some more choice reviews, some of which were only made available recently (this video was only posted within the last few months). Findings are catalogued below.

True to its nature as a precision platformer, this game is hard. (And fun.) Beating the Gold times is a challenge. Beating the Dev times requires detailed knowledge of certain game mechanics:

• Jumping repeatedly in small corridors increases your speed (jumping in an open area has no such effect)
• Picking up offspring in the middle of a jump does not decrease the height of the jump (you will jump as high as if you were not carrying the offspring)
• Thrown offspring can be picked back up in the moments after hitting a wall (they will otherwise fall faster than the player character)
• Bumping the edge of a platform while jumping up onto it -- or over it -- will slow you down a lot (it is much faster to land squarely on top of the platform)
• Bumping the edge of a button while jumping up over it will trigger the button (in this way, toggle buttons can be pushed twice in one jump -- once going up, and another coming down)
• Three impeccably timed button presses in rapid succession can allow you to pickup two children immediately after beginning a jump
• You can parry by facing an enemy (or enemy projectile) and tapping the arrow key towards the enemy (requires frame perfect precision, only works with Left or Right arrow keys)

And, of course, you simply need to become better at gracefully and perfectly navigating the light and fluffy player character off of, on to, and in between ledges.

AY-YIYI-YI-YI!
