Nice game, a little collision lags but other than that fun to play. Nice Job!

fun game, figured out if you get the right timing on the first pillow you can jump to the end

Some cool concepts!  I had more fun with the mechanics than actually playing the level.  The pillow increases your upward velocity each time, so you can jump REALLY high.  (Fun fact, you can actually fall so quickly that you actually go complete PAST the collision box during the Update().)  A game on just this mechanic would be interesting...

I think a setting the bounce to a static velocity instead of (I'm assuming) multiplying it would be necessary.  The T boxes could also use some mass (RigidBody2D.mass, since you're using Unity).  It pushes quite far if your X velocity is a little high.  Maybe just a touch more gravity?

Overall, good platforming.  The base is definitely there.  Would love to see this expanded.  Great job!
